I have a 14-bore hammerless side by side marked J N Scott and have no information at all on this gun. It is a relatively high quality sidelock but there are no proof marks, serial numbers, or anything (other than the name) to aid in ID, although I am satified the gun is an English import. I did learn that there was a J N Scott who headed up a very large Sporting Goods department for the Simmons Hardware Company of St. Louis; and suspect, with my gun anyway, it was an example named and marketed in the US based on Mr. Scott's reputation. I hope you get some solid information in your quest.
