Picked these for insulators up at a flea market yesterday. Nothing to brag about really. The CD 121 NEW ENG TEL & TEL has some nice amber swirling. The AM TEL & TEL has an upside down W instead of an M in the embossing. Checked all the others I have around and none are like this one. The O of Co. is the tiniest I have ever seen as well. I was very surprised a CD 126.3 with the two patent dates was among the rest though. Left behind a Hemingray Blue No 42 as well as some wooden pins and single metal brackets. Some other guy was supposed to come and buy the hardware and didn't show. The guy says he has more glass and would bring them next week. Can't wait to see what else he has.
