They are interesting guns and I am still looking for an example for myself. A friend has one and didn't realise what it was until I examined it for him. I believe Webley & Scott produced a few too. It would have to have been Proof tested before passing to the RAF to comply with the proof regulations.
I will quote from the book 'The Golden Century' by John Knibbs; 'Work on the double barrel shotgun was shelved at the time as all the drawings and tooling had been destroyed in 1940 during the blitz. During the war, what component parts of the shotguns that could be salvaged were assembled in both ejector and non-ejector models and were supplied to the War Office for issue to the RAF for use by airgunners in Bomber Command to learn clay pigeon shooting. It was thought that this skill would help them in aerial combat when using machine guns. Well after the war in 1960, BSA Guns Ltd. actually purchased back most of the surviving shotguns from the RAF stores together with ammunition. These guns, known as the Regent model, were refurbished in Birmingham and resold during 1961. As well as assembling shotguns using parts from their own production, BSA also refurbished and finished part made or incomplete shotguns of other makes and types requisitioned by the war office for use by the RAF. No records exist for these Regent Model shotguns but they can all be identified by the prefix letter W in their serial number'.
I think some must have gone to Fighter Command also as I recall reading in 'Johnny' Johnson's book Wing Leader that he used one. If only guns could talk! Lagopus.....
