CD 121 [110] (F-Skirt) AM.TEL.& TEL.Co. SB. I specialized in CD 121 AM TEL & TEL COs some years back and sold off a majority of the collection. I kept a few odd balls and this was one of them. This has what is commonly referred to as the 'Elmer Ring' on top on the pinhole suggesting it could have been made in one of the Lower Works / Upper Works in Elmer New Jersey. The color blue and glass appearance resembles the blue CD 252 Knowles and CD 256 Manhattans and come in. The pinhole is off center when viewed from the front and the glass drops down from the top of the pinhole like a marble. There are some nice olive swirls in this one as well which is among the reasons I kept it. No damage to report. Price $20 + shipping. PayPal Welcomed. First email as always!
