S. McKee Insulator

Reprinted from "INSULATORS - Crown Jewels of the Wire", August 1971, page 24

In the June issue you published a letter from Robert D. Cossaboom; he thought his insulators might be a McKee covered by patent number 107, 075. It isn't as you can see from the enclosed copy of the patent. So far as I know, none of these have been found.

In the same issue there is a letter and sketch from Paul E. Mohrs concerning a broken threadless he found. He suggests that it might be a "Leefers" (probably meant Lefferts). His insulator is larger than a Lefferts (C-6 in before threads) - in fact it's larger than any similar threadless that I know about. Id say it's a unique find.
