Need help identifying a .22

[Firespecialist]

I came across a .22 today at a gun show. The guy behind the booth new nothing about it, but had it for sale for $200. I didn't take up on it because I have enough .22s but it sure sparked some interest. He had part of a copy of the advertisement and it was priced for $14.95 along with an e-mail somewhat describing it. IIRC, it may have been a Mauser or Melvin Johnson design originally? I do remember the company bought the rights to it and the company was owned by a guy in the U.S. and after he died the company shut down. Other than that, I don't remember anything else. The link is the is the closest to what it looks like I can find. Hopefully, my curiosity won't lead me to shooting myself in the foot for not getting it...
