Old enough to be its own standard, for one -- the house that my maternal
grandmother lived in was built in 1905 and had that style of hardware in
it. 1905 wasn't quite Before Standardization, but it was certainly at a
time when standards weren't terribly prevalent.

Now I'm kinda curious -- and I don't know the answer!
