does it have a model number? I have been able to find a lot of manuals online or places with a manual simply by using Google.......
I also know that some Erma .22 pistols were made by Erma for American Arms....
I have an Erma .22 pistol that looks like a minature 45....wasnt listed under Erma but under American Arms which was stamped on the slide.
either one of these?
"Notes: The EP-22, also known as the LA-22, is modeled on the P-08 Luger, but chambered for .22 Long Rifle ammunition. It was produced from 1964-1971, and is basically of a similar size and of comparable weight to the Luger. Some rare variants of the EP-22 include the Navy model, with a 5.9-inch barrel (as opposed to the 4.5-inch barrel of the standard EP-22), and a Carbine model with an 11.8-inch barrel, wooden fore-end, tangent-leaf rear sight, and a detachable stock.
The KGP-69 succeeded the EP-22 in production, and was manufactured until 1997. It adds a magazine safety and replaces the wooden grip plates with a molded plastic grip. However, the barrel is shorter at 3.9 inches."
