This is a very unique flare pistol made by Waffenfabrik Bern. It features Swiss Bakelite grips, a WFB roll mark and a Swiss Army shield roll mark. These flare guns are 34mm and there are chalk rounds made for these. These flare pistols are unique because their barrels are quite long and even offer a mounting point for slings. The trigger guard acts as the release lever by just pressing the trigger guard forward, keep in mind the safety must be on for this to work. These were imported directly out of Switzerland into the United States by M+M Industries.
