If you don't know what the U number is for this one amybe you'll recognize the CD#'s of the glass insulators I will be posting in my next pic. Gotta tell you, if I were down to my last few bucks at the flea markets and a had to decided which to leave behind it sure would have been a tough choice. See all thye pics I post this round and I'm sure you'll know what I'm saying here.
