Regarding smaller English gunmakers, in the published book 'British Gunmakers', Volume Two, by Nigel Brown, pg. 139, under Rosson he states, "In the years before the Second World War Rossons, like many small gunmaking businesses started having a number of their guns made up for them to their specifications by the trade. Most of them were in fact built by Joseph Curry of New House Lane, Whittall Street and in many cases using high quality Joseph Asbury action and barrel machinings. The J A initials to be found stamped on the barrels of a number of Rosson guns of that period confirming their origins."
Interestingly, my 1915 Hollis, Bentley & Playfair shotgun barrels are also stamp marked J.A
