Stopping by a local shop today that deals primarily in high end shotguns, I noticed a double rifle in the used rack appearing to be in like new condition. It turned out to be a .450 3-1/4 N.E. bearing the John Rigby & Co. mark. The price was $17000, which struck me as unusually reasonable for a Rigby double. I did not look at the rifle closely, but it occurred to me this might be one of the California-produced Rigbys made on Merkel actions. Would this be a reasonable assumption? If the rifle is a Merkel, is it still a good buy?
