FROM WIKIPEDIA

The Ortgies 7.65 mm pistol was a hammerless semi-automatic pistol that was produced in Germany in the years immediately after World War I, first by its inventor Heinrich Ortgies and then by Deutsche Werke. Inexpensive, but of good quality, the pistol achieved considerable success at contemporary shooting competitions and, as an export product, was popular throughout the Americas.
