Hello,

We do not carry an exact match for the handle set shown in your photos but your mortise lock resembles the 82-229 depending on how the dimensions below compare to yours. This lock can be used with the 82-030 with 3-15/16" hole spacing.

With that being said, it seems like you may have a similar setup to the hardware shown in another customer thread where the lock plate is separate from the handle set, which you can view here. Unfortunately, we do not carry anything meant to install that way but review the specifications of our parts to see if you might be able to adapt them to work for your application. Thank you.
