We had acquired a casting from an original some years ago and had it re-cast with our name on the back. Unfortunately the original must have been mixed up with stock and mistakenly sold on, I’ve no idea if there were any markings on the back. A colleague of mine was a good friend of Andy Anderson and I have an original rig that came from him, as far as we know all of the buckles were different, some had more detailed hammering, some had the “A” on the back and some didn’t. He supposedly hand hammered them himself, I think it depends on when they were made. The buckle we have is the closest to the one worn by Eastwood.
