I recently acquired this and was told it was a model 1 22 rimfire. I hoped it would arrive with some legible writing on the barrel etc, but it did not. That is all well and good since I paid a very small sum and just wanted it to be in my Smith group. I figure some of you knowledgeable gents could help me out with date or any pointers. FYI I do not plan to fire the gun, but it does seem to line up well and does work, but it is pretty loose once snapped in place. Any help is greatly appreciated!
