This is Lot 1067 in the upcoming October 2019 Morphys Extraordinary auction.
Made by Señor Osorio in Nicaragua, this is a .22 rimfire caliber machine pistol with several clever design elements. It fires from an open bolt, using a .22-round Italian magazine of indeterminate origin. It has a selective trigger, with the top firing in full automatic (sliding rearward) and the bottom firing in semiauto only (pivoting). Aside from some sharp edges on the vz61-like folding stock, it is a remarkably well built and refined little pistol!

At Forgotten Weapons I think the most interesting guns out there are the most obscure ones. I try to search out experimental and prototype weapons and show you how they work, in addition to more conventional guns that you may not have heard of before. You’re much more likely to find a video on the Cei Rigotti or Webley-Fosbery here than an AR or Glock. So, do you want to learn about something new today? Then stick around!
