Need Help Identifying Parts to replace

A home owner from Colorado says:

The handle on the right is clearly not a correct replacement, but I believe I need to replace both sides handles and the mortise lock. I am not sure of the part numbers needed to make this start working again.

Thank you for reaching out to us. Your mortise lock setup is a bit odd. However, it looks like you have the 82-249 keeper which is compatible with the 82-265 mortise lock. Have a look and see if the specifications match up with your old lock. 

I'm afraid we don't sell dummy handles though. The best we can offer is the 82-089 which has no exterior key lock but it still has a thumb lever.
