DNS hardware replacement

I need a replacement lock for my patio door. Best guess is the door/lock are original equipment on the home, so about 20 years old.
The only marking I see is "DNS" stamped on the side of the lock mechanism.

I have included some pictures for reference.

Thank you
Jim

Hey there! Thanks for contacting SWISCO.com. It looks like you need our 82-227 mortise lock and 82-020 handle. Compare measurements and let us know what you think.

Your hardware reminds me of our 82-020 handle and 82-227 mortise lock, but carefully compare our dimensions to yours and see if these match what you need.
