Appreciate all the input, I contacted Jim Chambers, about the lock. Updated information on the lock from Jim.
Yes, that is one of our Late Ketland locks. I can't remember exactly when we started making that model, but it's been at least 15 or 20 years ago. With the large cock on your lock I can tell it is one of our early ones.
