There were thousands produced, made during the entire production run which started in the 1960's and ran for decades. It was not long ago that there was one of these hanging behind the cash register of every self respecting gunstore, more as anm object of display than as something they wanted to sell. When I worked at SARCO in the early 80's (which was an experience) we had... <scratches head> "lots" of them. We sold several weekly.
You have a nice semi auto Tommy. It's neither particularly rare, or particularly sought after as a collectors item. It's just a nice thing to have and play with. Enjoy it.
