THE UPSIDE-DOWN EMBOSSED EC&M AND RELATIVES

The upside-down embossed EC&M and the three others related to it have squared domes and a horizontal moldline around the insulator 3-7/8" from the top of the dome. All four have the same rounded mold dot. EC&M's F., G., and H. have a faint outline on the backside of the dome where the incorrect embossing was covered with a riveted plate. Height of these EC&M's varies only between the horizontal moldline and the base.


 

 
E. The upside-down embossed EC&M is one of the rarest EC&M's. The base on this one tapers down to about 1/8", is rounded on the bottom, smooth and finished quite nicely. This base is unique to the upside-down embossed EC&M. The vertical moldline over the dome terminates at the horizontal moldline. Besides my own, I know of only one and one half other upside-down embossed EC&M's. One is in V.N.M. condition; the other is just a "piece", and mine has a chunk of glass out of the skirt in back. Any others? The color is a moss green, a color I've seen in no other EC&M.
F. The squared dome, flared skirt is the corrected version of the preceding EC&M. This EC&M has the usual rough base, and the moldline over dome cuts through the horizontal line to the base. The colors I have seen in this style are: dark opaque green, aqua, and cobalt.

 

 
G. Excepting for the straight skirt, this EC&M is the same as F. Colors I have seen include: aqua, light green, bubbly apple green, and yellow green.
H.  This EC&M is the same as G., excepting for the rough lumps of glass in the wire groove at both moldline crossings and in front under the embossed M. Colors I have seen: aqua, dark yellow amber, and dark olive amber.

I have been collecting insulators for five years and specializing in EC&M's for the past two years. I will gladly answer any questions I can concerning EC&M's. If you have seen a color in any style that I haven't listed, please let me know the style (A-H) and color. Any other styles?
