CD 123 E.C.& M.Co. S.F. in beautiful bright cobalt blue. I believe this is an "F" mold style with the Dot on the back side. Very nice shape for these with two with a couple flat flakes up the skirt, a small base chip, and two base bruises - else just the normal nibbling at the sharp base mold line -- see pic. Nice tall version with a flared base (a full 4 1/4" tall!) -- $2250 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.
