There are “rare” guns and then there are guns that actually rare. This is one of very few Argentine .22 Service pistols that is not a conversion. This is an unrestored floating Ace style rimfire, produced in the late 1930’s. Not to be confused with the Sistema or Hafdasa 1911’s that were converted to .22, this is one of a couple thousand .22 training pistols ever produced under the Ballister Molina .22 patent. There really isn’t a market value on these, as they don’t really come up for sale very often, but Rock Island had one sell for $3,450 in 2021 (add below). It’s a cool, truly “rare” gun.
