Patio Door Replacement Lock

Question

I am looking for a replacement lock for my patio door. It is approximately 3/4" x 6 1/8". There are no markings on the lock assembly or the door.
I have attached pictures.

Thanks for posting. The parts you show seem to resemble our 82-106 turn lever and 82-227 mortise lock. Look them over and see what you think.
