more doorknobs and a caster

I TOLD Y'ALL?!! Last week when I showed another group of old doorknobs, I just *knew* that doing so would likely mean I'd simply find yet *another* bunch somewhere else -- and HERE THEY ARE?! (with a spurious old caster thrown in, because it was handy and found with them)

The one escutcheon plate here looks like it matches the others shown last week, I could guess the knobs here are also more likely than the others to have been 'sets' with them, but who knows -- I don't. Aside from the one painted pair all the top knobs are nearly identical steel, the lone white knob at the bottom is white ceramic with brass sheathed steel ferrule, it also is about half painted white.

The caster is also an oldie, entirely made of steel including its wheel. There are no maker's marks on anything, the knobs or the caster.
