Complete handle and lockset
Hello,
The design of your door is a bit unusual since the mortise cutout is recessed but the keeper appears to use spacers so that it is closer to the mortise lock. We can't guarantee any replacement parts without seeing the original hardware but I wonder if you could use something like the 82-226 or 82-227 depending on how the dimensions compare to your cutout and installation holes. We also offer the 89-020 and 89-02D keepers that are commonly used with these mortise locks.
As for the handle set, take a look at the 82-030. This is a versatile set as long as the 3-15/16" mounting holes match the ones in your door. Review each part to see if they might work for your repair. Please note that, unfortunately, we do not carry a dummy version of this handle set but you could install it without the thumb latch. Thank you!
