"W.W.96/73" is marked on the butt. This style of flare gun was known to be issued to the early U-Boats of the Imperial German Kaiserliche Marine. It is single action only and can fire either one barrel or both barrels at the same time.

Very fine overall with mild aged patina, some casting pits in the frame, light oxidation on the hammers, and minor marks and scratches. Mechanically fine.
