CCPU?? latch comparison

[wrndln]

I bought what I thought was a 28 to mid 30 CCPU door latch at a recent swap meet. When I compared it to a known CCPU latch I have, I noticed several differences. First the handle has a slight offset (first picture). Second, the main part is shaped differently (square) than the known CCPU latch which is somewhat rounded on the bottom. Third, there are no D nuts on the main plate to mount the latch, just holes. The gray latch mechanisms look the same as the known CCPU latch. Could the gray latch be for a model T? Any help identifying the gray latch would be appreciated.

I am attaching some picture I took of the questionable latch (gray finish) and what I am sure is a CCPU door latch next to it.
