Before he adapted it to .45 caliber for US Army pistol trials, Jens Schouboe was building his pistol design in .32 ACP (7.65mm Browning). It was a blowback action, hammer fired, and very quick and easy to field strip. The gun was reliable and well made, but just didn't catch on in the market, and not many were made. This particular one has a rather interesting feature of a second magazine latch location to act as a disconnect, firing single shots with the magazine held in reserve.
