As a final run, Interarms ordered and marketed a batch of 5000 HSc pistols, marked with an American Eagle on the right side of the slide. The AE was borrowed from the Interarms Mauser Parabellum, which had it etched on the chamber.
This particular pistol was not marketed by Interarms, it remained in Germany, had a normal HSc commercial serial number and was proofed in Ulm in 1976.
