I could not find any markings on this latch. However, I did use one of your single wheel that goes on the door bottom. If that helps. Also I believe this home with this slider came out of Canada.

Please see our 82-036 handle set, I think this may work for you. I'm afraid we do not carry the mortise lock or keeper, unfortunately.
