I think at that time that was the only Bedford lock on the market. A friend has a Bedford built about that time that had one of these early Hamm Bedford locks in it. We had to put new works on the old plate when he wore the Hamm internals out. It was not an easy job. His gun has a Paris OTR barrel in it. I don't think there were many, if any, barrel manufacturers doing swamped barrels back then.
