My final set of the evening includes this group of books by Jack Tod. If you've ever had a whatsit to identify (knob, spool, cleat) chances are you will find it here. I believe the Insulator Patent book covering patents from 1880-1960 is a great resource to identify oddball porcelain not found anywhere else.

Also included is: Porcelain Insulator Guide Book (1971) and the 2nd and 3rd editions of that book, A History of Electrical Porcelain in the United States, and Supplement A & B (1972-1973). All books are like new with the exception of the jacket on the hardcover Guide Book from 1971 which is torn in a few places.

From a smoke free home. A must have for the porcelain collector who does not already have these long out of print books.

Let's go $40 shipped on this group.
