Here's a beautiful CD 164 in the alternate fat wire groove variant that is believed to have been acquired from BGMCo after losing their lawsuit to Brookfield. Embossed BROOKFIELD (front) NEW YORK. (reverse). Notice the period after the K! I believe this is a remnant of the period after the former "BGMCo.". Backwards 4 on dome.

Has one tiny flake on upper wire groove and a few very tiny nicks on the inside of inner skirt. First email gets this tough insulator- hard to find in this color! for only $50 plus 10 shipping. Thanks!
