This is a CD 102 pony - embossed (front skirt) B.G.M.CO. It looks like there is a number 8 on the dome - it is tough to tell for sure as it is in close relationship to the open bubble described below.

Being critical of the condition: there is a peck on the dome at the side, a peck on the top part of the inside of the wire groove at the rear, some roughness at the outside edge at the base and some tiny cooling lines in threaded area. On the top of the dome there is a shallow, narrow 1/2" line that looks to be an open bubble. It is as close to mint as you will find - you may never be able to upgrade this piece.

This insulator would look good at your house!!

This piece can be yours for $125 - includes shipping and insurance in the US (will work with those from Canada). Payment can be made by check, money order or PayPal.
