Need lock & handle replacement

Thanks for posting! Your handle set appears to be part 82-086. Look over the dimensions and compare them to your original to confirm that this is the right fit. I am confident this is the right replacement for you.

Dimensions for 82-086

Please be aware, the internal mortise lock is not sold as a complete set.

I'll need to see a photo of the lock to determine the best possible recommendation. There are few compatible with the handle set you have.

It would also help to provide the measurement for the distance between the installation holes from center to center.
