CD 106.1 GLASS CO // "dot" (dome) 6 -- I can see no sign of DUQUESNE on the side with the dot. It is possible that it just never got pressed -- bonus points for a great cornflower shade and nice condition -- $200 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.
