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. The most prolific of these was the No.1 produced at the company’s Birmingham facility in the later stages of World War I.
Signal flares were not intended as a weapon. They were used on the battlefield to communicate certain activities. For example, a green flare was shot in the air to indicate enemy position captured.
