This insulator is a CD 1052 with NO Embossing. I believe it may be a Whitall Tatum product. The spool is filled with tiny bubbles and is a straw color. It is in nice condition with a top edge 1/2" fingernail chip. The insulator leans to one side probably from not cooling properly. A number of these spools were found in the Helena MT area many years ago. $75.00 plus shipping. Payment by PayPal friends or check. Thanks.
