Looking for Kaufmann & Roller Bridge for a 325

[Severin]

I am trying to find a pair of chrome knobs, a Kaufmann vibrola, and a roller bridge for a 325 ('58 -style). Anyone got a set from a refitted C58 or know where I can find one? Anyone have a real set they'd want to part with? (I realize how unlikely that latter is, but it never hurts to ask....) Any help would be greatly appreciated.
