Thanks for posting. This mortise lock looks like our 82-229. Please compare the dimensions below to your old hardware to see if it matches up.

. If your handle set is damaged you should be fine reusing it; otherwise, our 82-087 should work as a replacement. Let me know if you have further questions.
