Dear Jack:
I found this interesting porcelain insulator in an antique shop here in New
England and could not find a U- number for it.
It's similar to the U-344A but is a Skirt Rest type instead of extended
petticoat.
The crown is more flat and also larger. It has a heavy MLOD, and the
indentation in top of the pin hole as on many Pittsburg High Voltage insulators.
Very fine brown glaze. Would be interested in learning more on this insulator.

Dear John:
A great find. All the other "wide hats" as made by PHV and all
other companies are extended-petticoat types, so we're adding this new one to
the Universal Style Chart as U-344B. I made the above drawing (1/2 size here)
from your dimensional data and on the assumption this was made in the same
forming molds as their standard #58 but with a different petticoat jiggering
file. I have specimens of the Pittsburg No. 58 (Sim U-344A), and their contour
is as shown above.
Would be interesting to find out if any other readers have ever turned up one
of these. Anyone specializing in Pittsburg insulators would sure love to land
one of these.

Dear Jack:
We would like some info concerning a marking on an insulator. Our youngest
daughter has gotten interested in collecting and in two short weeks has
accumulated some that have taken us two years to acquire, Ah, blond youth!
She stopped by today with a U-705 Locke which has the Locke #7 marking in
your book but also with a P aside the normal marking. We went thru mine
hurriedly and found a larger cable, but it has a B by the normal trademark. What
do the letters P and B on these mean?
Borrowed a book on porcelains by Gerald Brown and found it real interesting.
Have many illustrated in his book. Can't believe the prices on them. Are they
for real or just a guide?
I would like foreign insulators. Any place you could suggest we might acquire
them?

Dear Pauline:
Yes, Locke Insulator Mfg. Co. did occasionally use factory code letters with
these #7 markings (1922-1928) and also with the earlier "VICTOR"
markings. The "B" is the one most commonly seen with the #7 marking.
Similarly, other companies used various types of code markings for different
reasons. From factory records and talking with older plant employees, we've
decoded about half these scribbles; the other half will probably remain
mysteries.
All the evidence seems to indicate these Locke codes on skirts of small pin
types are for trimmer operator identification. Pinco and Lapp also used skirt
letters for the same purpose.
Yes, Gerald's various books are excellent for general reference, and I know
of no collector who would be caught without them. However, the prices in them
are definitely not for real. I suggest you ignore them and just use the books
for their other benefits. (See separate article on pricing porcelains, end of
this month's column.)
To get some foreign porcelains, discover the fantastic pulling power of CJ
classifieds. I'm sure many collectors have them to swap or sell.

Dear Jack:
... Also I would like the address of where I can order patent copies, plus
information they need. You printed this about a year ago, but I couldn't find it.

This was in the January 1975 Crown Jewels page 20. For the benefit of newer
subscribers, we'll repeat it.
Address: Commissioner of Patents, Washington, DC 20231
Send either (1) the patent number, or (2) the full name of the inventor,
approximate date the patent was issued and a description or name of the patented
item. The price is $.50 for each patent copy ordered.
Don't hold your breath waiting to receive them. It takes from one to three
months to receive copies.
PRICING PORCELAIN INSULATORS
Pricing glass insulators is relatively straight forward, since there are only
about 3,000+ different ones counting the collectable unipart and multipart pin
types, foreign and U.S., threadless, guy strains and miscellaneous. That
includes all known combinations of style, color and marking variations!
Porcelains are a different kettle of fish. We have approximately 950 uniparts
(so far) in the Universal Style Chart. If you consider all the possible
combinations of style (shape), color and marking, there could be 50,000
different porcelain uniparts (U.S. only).
If you wanted to add all the multiparts, the small ones to gigantic ones, the
very old to the very modern, that's another 50,000 possible combinations.
It would be impossible to print, much less lift, a book which attempted to
price all the known porcelain insulators, not to mention the endless stream of
new ones that turn up every day as collectors search all the back corners. And
there is no person, or even a committee of people, who could arrive at prices
which would approach the median of all parties buying or selling insulators.
There must be some good way to approach the pricing of porcelains, but thus
far we haven't been able to get our hands on it. From studying the failings of
our past attempts, I have some ideas to a new approach, and work is being done
on that at this time. The following paragraphs describe some of the approaches
attempted thus far.
In my book, "Porcelain Insulators Guide Book for Collectors", I
attempted to offer a method which would allow any unipart pin type to be priced
by considering the only four factors which make insulators of interest to the
collector -- the style (shape), the color, condition, the rarity or desirability
of the marking.
The method involved setting a base value for any given style (U- number) on
the assumption of it being a mint specimen of the most common color and most
common marking. Then charts were given to indicate just how much better the
insulator was if it had a more desirable color or a rarer marking.
The system worked beautifully -- in principle! Even an inexperienced
collector could take any given pile of pin types and compute prices for each
that were always right on the button.
But there was a flaw. It was too complicated for the average person. Even
dedicated porcelain buffs who gave it a good try threw in the towel when they
came to the place requiring some addition or multiplication. People with a more
casual need for pricing specimens took one look at the pricing in my book and
never even attempted to understand it.
I have had no end of criticism of the pricing method in my book, and I'm sure
most of this criticism is just. I tried to be idealistic with a system which
gives perfect results, but the problem is some collectors would not make an
effort to understand the basically simple system.
What we really need then is a book about 20 feet thick where, with a suitable
index, a collector could ultimately turn to a page with a full size, color photo
of his particular insulator specimen, same color, same marking, same condition,
etc. Under this photo should be a price printed in 30-point type, preferably at
least $50 for any insulator in the book.
I still believe my approach was correct in that any insulator could be priced
considering the three factors of importance (assuming mint) -- style, color,
marking.
But it would have to be done on a much more simple method than I set forth in
my book.
Frances M. Terrill in her book, "Porcelain Insulators Photographed &
Priced", did come up with the best approach thus far. Each item is shown
with super-clear photos and with a word description. A price followed. The
prices throughout are fairly realistic, but a number of the more common items
(not all of them) tend to be priced a little on the high side. Of lesser
consequence, several of the more rare items are priced too low; hopefully
Frances sold this book to a number of antique stores we frequent!
But I still highly recommend this book to anyone who has a casual interest in
porcelains. It is especially suitable to people who have no knowledge of or
interest in porcelains and just need a book to guide them in what are the
goodies and what are the nogoodniks. Even though the book lists only several
hundred different porcelains of all types, it is possible to relate given
specimens to similar ones illustrated and arrive at a ballpark guess in value.
The book has limited value as a pricing tool for active or advanced porcelain
collectors because it illustrates a relatively small percentage of the rarer
insulators -- the many -unusual insulator styles, the many rarer markings. It is
well worth its $3 price on all other counts.
Gerald Brown's various books are positively indispensable reference tools for
any porcelain collector, and I'm sure there is no active collector who does not
use them constantly for reference as I do, However, the pricing in them is
valueless. Actually, because of the severity of the errors on both the low side
and high side, more harm than good will result by attempting to use the price
guides in his books.
Gerald uses an incremental price code for each item, - wherein each increment
is a $5 increase in value. This is completely inflexible in the price range of
95% of all the porcelain insulators that are illustrated. With the first
increment (1 star) representing all values from zero to $5, it is impossible to
indicate that a given $3 item is three times better than a $1 item -- or thirty
times better than a $.10 item.
The more serious harm that arises from this guide is the gross overpricing of
common to nearly worthless items -- a complete disdain for the welfare of fellow
collectors who might use this guide in their dealings. There are numerous $.50
to $2 insulators priced with two stars ($5 to $10 value). There are even nail
knobs ($.10 items) priced with three stars ($10 to $15 value)!
Although of less serious consequence, there are some items underpriced. For
instance, the U-189A (a $75 item mint) is shown as a three-star value ($10 to
$15). Would you trade your U-189A for a nail knob, also rated by Gerald as a
three-star value?
So there you have it, the difficulties of the neophyte porcelain collector
trying to determine porcelain values. It isn't really a problem for advanced or
very active porcelain collectors who know the goodies when they see them and how
much they are worth -- and summarily ignore all published price guides anyway.
Is the beginner then at the mercy of the other fellow when he starts to buy
or sell something? No, unless he is either in a hurry, or too indifferent to
really care.
Any collector who does desire to learn a little about the values of
porcelains can't help but get a quick and reasonably accurate education by just
observing the price stickers on show tables and by scanning the various ads in
Crown Jewels where items are sold competitively.
If you just look at the insulators in your own collection, in the collections
of others, in the exhibits, on the show tables, you very quickly learn what
everyone else has in abundance or what no one else has been able to locate and
consequently may have high value.
You soon learn that absolute rarity has positively no bearing on porcelain
prices. What does count is absolute desirability! Even a unique specimen of a
large, modern, brown cable made by Ohio Brass might never sell with a $1 sticker
at any show. No one wants it.
Yet you could sell cobalt blue Roman Helmets at $20 a clip as fast as you
could wrap them even if you showed up with a trailer load of them. Everyone
wants it.
This kind of thing then leads to some generalizations which help greatly in
making horseback guesses on porcelain insulator values. Regardless of what price
guides you may have seen, let your own intuition assist you in deciding
reasonable price ranges for various items.
If the insulator is a very ordinary-looking brown pin type, either unmarked
or from a big company, chances are it's a $1 to $2 item at best. As opposed to
glass pin types, largeness is more of a liability than an asset.
Practically all the special purpose pin types (mines, transpositions, eared
cables, fog bowls, etc.) have more than minimal values. Even common varieties
without special color or rare markings are in the $5 to $10 range. Some of the
tougher ones to find are worth two to three times that, and there are a few very
rare ones worth considerably more.
Any pin types with special glaze colors (blue, green, yellow, mustard etc.)
are considered desirable items, and even common styles in "color" are
$3 to $5 items. Any of the special styles in "colors" are uncommon and
can be worth a considerable premium over the common-colored ones.
Virtually all the very early items made by Imperial, Thomas and Fred M. Locke
are desirable items. And in this particular case, largeness may enhance the
value.
In the case of porcelain insulators other than pin types, you will soon learn
that not having a threaded pin hole for use on crossarm pins is two strikes
against any potentially high value for the specimen. There are some exceptions
in the case of very old specimens or highly unusual gadgets of known usage, but
these are few. Miscellaneous equipment bushings and the like are very pretty
items that make nice go-withs, but the average collector will not pay a high
price for "oddballs".
All forms of wiring insulators and various "standard porcelain"
items are real fun items to collect and usually involve more interesting
histories than ordinary pin type insulators, but their collector value is very
low. The exceptions are unusual "patented" forms of special knobs and
cleats. Anyone collecting these small insulators is liable to pay substantial
premiums for unusual, rare ones they do not have in their collections.
If you are a beginning collector or a noncollector needing help in pricing
specimens, keep in mind that any collector knowledgeable in porcelains will
always be quick to assist you in valuing insulators. If you are buying (or
selling) insulators at a show and need a price check on any insulator, check
with some other party before you make the purchase or sale.
Lastly, keep in mind that if you yourself are happy with the purchase you
just made, that's what counts. Some insulators may turn me on to the extent of
$20, but you wouldn't want them for $2 -- or vice versa. It reminds me of the
time when I bought an item and commented to my buddy as we walked away about
"how I really stole that goody for only $12"-- only to overhear the
dealer behind me telling his buddy how he "really took that pigeon with
that piece of junk he just sold for $12". If both buyer and seller are that
happy about the deal, the price must have been o.k. -- regardless of what any
price guide said.
