In the late 60s, a family friend taught me to shoot a .22LR revolver. It had the profile similar to the Arminius w/o VR or the square butt High Standard Sentinel. Nickel plated, plastic grips, 3-4" BBL, DA, 8-9 shots, fixed sights and the cylinder came out when the cylinder pin was removed like the NAA minis. The pin was then used to poke out the empty cases. Any ideas who may have made this and a model name??? It was not a new gun in 1968. The old family friend went to that big range in the sky about 15 years ago so he is not a source of info any longer.
