HELP NEEDED with Solid handle lock sets

A home owner from Boston Mass. says:
I have taken a few pictures which I hope may help your research folks to find a best match. As you see, the name on the original lock set is CROWN. The hole/opening in the door when this lockset is removed (see photo) measures 2 cm x 18 cm.

Hello! Your lock looks a lot like our 82-008 patio door lock. Check it out and let me know what you think!
