This CD 145 is a base embossed THE STANDARD GLASS INSULATOR CO. BOSTON MASS. A nice light blue color. There are two pin pricks on the dome and a 1/2" glass scratch on the skirt. A bit of fine chipping on the first thread. Not dead mint, but one that will be tough to upgrade. I was suprised to find two of these in a small collection I just acquired. They are getting harder and harder to come by. I`ll offer this one for $225 and that includes the shipping cost. I will also post the other one for sale tonight. (it has been sold).
