CD 190/191 -- (top) B -- nice deep green -- open bubble on the base on the back side -- (bottom) also green, but not quite as deep as the top -- open bubble on base and nibbling around the top of the base where the glass plug is removed at the factory -- $75 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.
