Can't find any name. The lock is about 2.25" long less handle. About 1 5/16" high and 11/16 wide at the top and 3/8 wide at the bottom. Separate "cams?" in the center.

Hello! Thanks for reaching out to us. It sounds like you're looking for the key tumbler. The 40-089 and 40-123 come to mind though we can't promise they will be compatible with your existing mortise lock. Have a look at the specifications and see how they compare with yours.

The workings of 089 look correct with the two separate center parts. But it has the wrong shape. The 123 has the right shape but a different center part. I don't know if that makes a difference in the operation. With the existing one, the key turns one half of the center part to lock and unlock. While the thumb knob actuates the other half to lock and unlock.

I'm not sure if either key cylinder will work on your locking handle. You might need to replace the complete handle set. I recommend you have a look at the 40-049 handle set to see if this is something that can be adapted to your door.
