It was an Erma Luger, imported by Stoeger from the late 60s through the late 70s, if I recall correctly. They had a cast pot metal frame, and varied in quality from poor to fair. Parts are no longer available, and were tough to find even when they were in production. Interesting little guns, primarily due to their resemblance to a real Luger. If I recall correctly, Erma was a German company, don't remember what the name stood for (Erma Works or something similar). Some are probably still around, although finding one in good condition may be difficult.
