Interior handle and mortise lock for sliding glass door

A quick learner from Napa, CA says:
this is an older sliding glass door that is missing the interior handle and locking mechanism. The exterior handle remains. Probably a standard sliding door for the 1990's.

Thank you for contacting us. This looks a lot like our 82-080, Sliding Patio Door Handle Set. Check it out and see if you agree. I'm afraid the inside handle is not available by itself.
