Collectibles--General (Modern)/CD 121 Early Prismatic Style
I purchased this at a flea market this weekend and tried to do some research on line about it. As I read I found out that some read A.M. TEL. & TEL. COM. or they will have no dots at all.
Mine reads A.M. TEL & TEL. COM. no "." after the first "TEL" Thanks for your help.
Pictures are attached.
Hi and thanks for your question,
These CD 121 Am. Tel. & Tel. Co. styles were made by a number of different glass works as well as in large volume. A.T.& T.Co. was trying to standardize insulator designs so they could get consistent results from different glass works. There are a huge number of variations in punctuation with periods and no periods. The price guide does not cover all the variations. A collector could have a lot of fun trying to locate all the different markings and mold variations in these. I suspect yours is a Brookfield product. I don't think the various differences in periods makes a value difference, but clearly it designates a different mold.
Hope this helps, Thanks, --Bob
