That gun not only has the A&D patents but also the C-bolt. As I said in my first post, I do not believe anyone but WR built guns on the C-bolt top lever platform. I could be mistaken on that point but I do not think so. My guess, at a minimum the barreled action was built up by WR, possibly the whole gun and simply branded Hollis.
Not all Richards had the set screw, but the shape of the lever is definitely different, this an early Richards maybe there was a transition period for the lever and design.
