Picked this up on a trade fellow hunted it every year for deer. Anyways I don't know much about these and was wondering what I have here. Here are the pics. Any input is appreciated.

I remember when these were being sold by International Firearms (Century Arms) in Montreal. '60s. Economy Spanish gun. Don't know if they were being made as reproductions, or if they were originally intended for 3rd world markets.
