As for 1920's wiring, anyone have any online resources they really like? I'm finding a bunch of oddities, and would like to know their history.


This is about it. If you've found any old catalogs, codebooks, or textbooks, by all means share what you know. It's kinda DIY. I recommend any old books by Terrell Croft as a starting point (e.g. early editions of the American Electricians' Handbook). You might also check out Kilokat's site.
