I'm always in search of any Canadian insulator manufacturer or distributor catalogues. I'd be tickled pink to find any catalogues from any of these manufacturers:

Canadian Porcelain

Canadian Ohio Brass

Slater

Hayes

Canadian Line Materials

Canadian General Electric

Medalta

National Porcelain

Smith & Stone

Dominion Glass

Diamond-Flint Glass

Sydenham Glass Co

Diamond-Flint Glass Co

North American Glass Co

Canada Glass Works

I can dream about someday finding any of the earlier manufacturers at the end of the list. I'd be outright ecstatic to find any of these.

If you have any Canadian glass or porcelain catalogues at all I'd absolutely love to see them. Please feel free to reach out!
