Need help with locking mechanism

A quick learner from Virginia Beach, VA says:
I'm looking to replace this locking mechanism. The handle the goes to it is also in one of the photos.

The metal lock is 9" in length with 4 screws. Do you perhaps have a similar part?

Hello,

Your mortise lock resembles the 82-238. Take a look and compare the dimensions below to yours.

The 82-080 handle set is generally used with this mortise lock but it is clearly a different style than yours. The 82-238 would still work as long as your handle set used the same type of thumb latch as the 82-240 shown below. Take a look and see what you think.
