Unidentifiable Mortise Lock and Handle

A home owner from Montgomery, AL says:
Security Screen door with no markings other than a white sticker with a barcode and serial number 0000881791 on the hinge rail. The handle was sticking and eventually broke. The broken part is a piece within the lock body connected to where the spindle is inserted. I would like to go ahead and replace the handle along with the lock body if I can find one slim enough to fit the door.

Hello!

Your handle set looks similar to our 40-193 but you'll need to compare our dimensions with yours to confirm this matches what you need.
