John , I wish I knew the answer. It is nitroproofed about 10 years ago, weighs 6#, and is marked as #2 on the top rib. The top rib reads William Moore & Grey 43 Old Bond Street London 2. If it is a conversion, I cannot tell it, but the reproof covers the older proof marks. Now, let us find Number 1.
Would it being a 16 bore give more weight to it being a converted muzzle loader ? Of course the gun cannot be opened or closed unless the gun is in at least half cock position.
