Insulator CD 121 (?)

[captcadillac]

I collect CD 121's (at least I think that they are CD 121's)
Thought I'd try a picture of one of my shelves.

Yep, those are CD 121s... also known as "tolls." That's a nice variety of colors you have there!

Hey thanks for the compliments and confirming my insulators as CD 121's. I have been collecting them for years now and when I would buy one I would ask is this a CD 121 and of course they would tell me they were. However I really don't know insulators very well and for me the other closely related insulators look similar.
