Constructed mostly from brass with steel hammers and triggers. In function, this flare pistol resembles the later production German double flare pistols, with a side-by-side barrel set. While the history of this particular flare pistol is unrecorded, this style of flare gun was known to be issued to the early U-Boats of the Imperial German Kaiserliche Marine. Operation is single action only, with the hammers set into rounded housings and controlled by a single trigger which can fire both barrels with a single long pull or just the left barrel with a shorter pull. Produced without sights, with a pair of smooth grip panels.
