old sliding door locking handle parts needed

A home owner from Austin Texas. says:
We have a houseboat built in 1987 with three glass sliding doors. One locking handle
works. One locks only from inside. One is missing the lock device. As the framework includes the specific type locking receptacle we must use the same lock again presumably. The name and number inside the handle is Allen Stevens R D 1965.
Are you able to help us please? I can add photos later today if necessary.
Thanks, Deborah

Greetings. Allen Stevens has been out of business since the turn of the century. We believe you are looking for our 82-003 lock. If you need a keyed outside pull, see the 82-306. For the keeper, see our 89-007
