July 1974 ECM S.F. Insulators Part I

The three dome styles are: rounded, beveled, and squared. All EC&M's have flat domes, with the top edge rounded, beveled, or squared. The two skirt styles are: flared and straight.

The dimensions of these drawings (following pages) have been scaled directly from insulators in my collection. No EC&MC-S.F. insulators have been found in Alaska.

A.	The rounded dome, flared skirt is the only EC&M without a mold dot. I have observed rounded dome EC&M's in the following colors: light green, dark lime green, dark emerald green, powder blue, washed out cobalt, cobalt, and dark ink blue.
B.	This squared dome, straight skirt is also known as "flat top, square dot" and "flat dome". Colors I have seen: green, aquas, dark yellow amber,. dark olive amber, and blue.
C.	The beveled dome style has a distinct bevel on the top edge of the dome. This style has a rounded mold dot on the front skirt. Colors: aquas and apple green.
D.	The beveled dome, sheet metal moldline is the same as beveled dome "C" except for the different moldline. This one is also known as the "tin mold" EC&M. Colors of this style I have seen include light blue and aquas.

How many collectors know what the upside down embossed EC&M looks like? Coming soon: EC&MC-S.F INSULATORS, PART II, THE UPSIDE-DOWN EMBOSSED EC&M AND RELATIVES
