Pictured on the left in this pic is a CD 134 AM Insulator. The closest index number I could find to discribe this insulator is [040], but is it? I ask this question because this is the second CD 134 like this one I have found. Both this one and the one I found last year have an extra period not listed under any index number. below is the [040] listing verses what is embossed on the base of the two I have. Notice the extra period before C of CO.

[040](Base)AM.INS.CO. PATd SEPT 13.'81. (Glass dots)BE [0?0](Base)AM.INS. .CO. PATd SEPT 13.'81 (Glass dots)BE

Has anyone out there in ICON land run across this same situation when looking for the exact listing? And, what's the story here. I'd find it hard to believe this would be an unlisted insulator. Please email me with any info on this and also let me no what the latest membership fee would be for those wishing to become members here. Thank you.
