Here is a scarce CD 193.1 AM. TEL & TEL Co. transposition top. this is tiny compared with the larger CD 191 -- has a nice ribbon of milk. I don't really see any issues - maybe some tiny pecks -- say VNM+ -- $295 plus actual postage.

NOTE: I'm selling these insulators on behalf of the Jim Fielding estate -- PayPal (no fee friends and family) or checks are both accepted - I'll provide instructions. I'll also be handling all the packing and mailing.
