This is a B-mold, CD 123, EC&M. Photo taken in a base-lit display case. The base is much better than many EC&M's This one was dug in the commercial district of San Francisco back in the 1970's

I am looking for an equally unique CALIFORNIA insulator to put in my display case or a great color example. Cash to even out any trade. Email me for my want list. Thanks.

Sorry, sold at 2013 Rohde Ranch Tailgater.
