Need replacement lock and handle for sliding glass door.

Hello,
I'm trying to identify the correct replacement mortise lock and matching handle for the original sliding patio door in a Redman manufactured home built around 2002–2008.Unfortunately, while removing the handle, the original mortise lock fell down inside the hollow door stile and cannot be retrieved. The original handle has also been discarded.I have already purchased several replacement mortise locks from local hardware stores, but they were all incorrect. The most common issue is that they had square-ended faceplates, while the original lock had rounded (radius) ends.Here are the measurements and information I have:Handle mounting screw spacing: 3-15/16" (center to center)Backset: 1-3/4" (door edge to spindle center)Lock type: Single hook mortise lockFaceplate: Rounded (radius) endsOriginal edge opening has been modified slightly during previous repair attempts, so it should NOT be used for identification.Internal steel pocket is approximately:3.25" tall0.50" wide1.50" deepI've attached photos of:The handle mounting holes.The edge of the door.The strike/keeper.The complete door.The tape-measure photos.The glass etching.Can anyone identify:The original mortise lock.The correct replacement mortise lock.The matching handle set or complete replacement kit.Thank you very much for your help.
