Webley & Scott produced a number of single-shot, break open signal flare gun devices used by Commonwealth Military Forces during the First and Second World Wars. Perhaps the most prolific of these was the No.1 MkIII, produced in 1918 at the company's Birmingham facility. A variant, differing only in its use of black plastic grip panels instead of the earlier wood, was produced by Colonial Sugar Refinery in Sydney, Australia in 1942. The pistols can often be seen in films, notably Lawrence of Arabia, where the title character discharges one to signal the beginning of an attack on a disabled enemy train, and The Empire Strikes Back where bounty hunter Boba Fett is seen carrying one as a rifle.The first image is of one of these guns on display at the National Firearms Museum:
These next three images are of one of these guns that I inherited from my grandfather. This one was manufactured in 1916 (MkI). I'd like to find some flares that would fit it and fire a few rounds on July 4th. Would I attract unwanted attention? ☺
Take note - I don't know the back story as my grandfather served in WWII and this gun is WWI vintage. I suppose it still may have been in use and issued to him during WWII, but I don't know that. It might also have belonged to his father. If you have parents and grandparents alive now, find out your family history before they're gone when much of that history goes to the grave with them.
