Your lock appears similar to our 82-008, which was made by DNS industries. I'm afraid they've been out of business for some time now.

This also means I'm unable to identify the door manufacturer, since many, many companies used DNS hardware. There is no way for us to identify the roller unless we can see it removed from the door.
