Here is some good information; "In addition to being a gunmaker Charles Boswell was also an expert shot in the sport of live pigeon shooting. A connection was soon built up based upon his prowess as a shot and skill as a gunmaker and in 1884 he moved to more prestigious premises at No 126 The Strand. The first gunmaking Charles Boswell had served his time (apprenticeship) with Mr Thomas Gooch of Hertford who was first listed as a gunmaker in Hertford in 1834." Sorry, but it doesn't appear he had various grades or models of guns.
