Patio door handle

Hello there. This setup looks a bit unusual, but I think we can help. Can you tell me the hole spacing, or the distance between the center of each mounting hole, on the handle set? Can you also show me the mortise lock in the door the handle set works with? That should narrow things down.

Thanks for getting back to me. Based on that dimension and photos, the 82-080 Handle Set is our best match for this setup. Take a look and see what you think. Let me know if you have further questions.
