Patio Door Handle

I am trying to identify this patio door handle that is on my living room slider. The house was built in 1962 and I believe the handle is original. The backplate of the handle is 5-1/2"w x 1"w, the wooden handle is 9-3/4"h x 1-5/16"w, and there are two screws attaching it to the door that are 3-7/16" center to center. Unfortunately, there are no markings of any kind on the handle or door so no way to identify the maker. Please help!
