Please help me identify this part so I can order a replacement.

We have two possible replacement options. The first is our 40-198 mortise lock, with a depth of 1-1/2". The second is our 40-211 complete handle set, whose mortise lock has a depth of 2". See if either of these match the dimensions of your latch.
