SOLD Here is a group of 10, CD 121 insulators that would make a good starter collection for someone wanting to start a 121 collection or add to their current collection. The embossing of the insulators include Diamond, BTC, Brookfield. And Hemingray (though the embossing on it is Hemingray). The value of the insulators book at $80, but I am only charging $40 for the insulators plus $20 shipping for the insulators, any where in Canada and mainland USA. If you would like to know some of the specifics on the embossing of the insulators, etc. Please contact me at discover@cpnet.net
