I have about 140 CD 102 insulators of various make. These are all good pieces w/out major chip or issues...no junk here. I'll only keep a handful for my collection. They have all been identified by make, EIN and color. If you need a particular CD for your collection or your study, I'd be happy to see if I have it and if so...we can work something out. I've seen plenty of mold numbers, SKEBs & CREBs, embossing variations & errors...you name it, it's probably in that pile of glass on the table. The bigger pile on the left is pure Brookfield while the smaller pile on the right is everybody else. Seemed a waste to have this much variety and not open it up to the community. Thank you...Zaph
