Hello all,

I'm hoping someone here will be able to identify a part I need to fix an old mortise lock. I'm looking for a piece for a 65+ year old residential mortise lock that mounts in where a mortise cylinder would normally screw in, but acts as an actuator for a thumb turn.

The thumb turn is nearly identical to this one http://www.houseofantiquehardware.com/v ... turn-brass

The piece I'm looking for can be seen in this photo in the bottom left part of the case.

Additionally I could use a good source for spare parts for older mortise hardware. There's a Baldwin distribution center in town, but they don't have much in compatible parts.
