This is an interesting piece of Eastern Bloc history. During the Second World War the Romanians contracted production of these flare guns from the Soviet Union. The pistol is a 26.5mm steel frame flare pistol with aluminum grips. The aluminum grips are more uncommon compared to the wood grips model.  This flare gun has an exposed hammer and a release trigger Infront of the actual trigger guard, this trigger opens up the flare pistol to remove spent shells or insert a new flare. There are chalk rounds made for 26.5mm flare pistols. These were imported directly out of Romania and have varying conditions. Finish may be intact or not, but the overall quality of these flare pistols is good for Warsaw Pact military surplus.
