I was in contact with Peter Powell, doing some research on my gun. The records he had for the shipment to Schoverling and Daly in 1870, that included my gun, had a couple of revolvers, marked Wm Powell and sons. He said whoever did the final finish work on the gun usually signed them. There was also a used percussion Westley Richards in the order. I doubt revolvers were made in house, the tooling would be completely different and complicated. Howdahs are very similar to shotguns and the barrels are usually the same bore. I am pretty sure the howdahs were made in house but revolvers seem unlikely.
