In reply to the letter by William Bramlett in the "Research Division" of the December Jewels.

Most CD 143 Dwight/Pattern insulators in both the flat base and round base types have the block out letters preceding Dwight in varying degrees, depending on the sharpness of the molding.

The G.N.W. Dwight/Pattern insulators which I have found in only one small area in south-western Ontario, all are the flat base variety.
Keep up the excellent work.

Enclosed check for renewal to Crown Jewels. Also photo (above) of Texcoco No 9, green color, sharp drips. Have sent information to Milholland, who told me he has never seen one.

Also photo (below) of insulator that has embossing IL NS 80, which I believe is either French or German.

Need information on this insulator. Also sent to Milholland.

Dear people,

I recently obtained a CD 152 Brookfield No. 48, green with some snow. On the back side, to the right of the No. 48, about an inch from the base, appear the backward letters FI, like this ... There is no trace of letters before or after. However, the letters are recessed into the glass. Although they are not very deep, it is obviously machine made, and the characters are the same size and style as the Brookfield on the other side. Is this some kind of bizarro, or is it common? I have never heard of an insulator like this. Explanation, anyone?
