I bought a French 22 pistol a few years ago. The brand name was "Unique." No idea if it even had a model name. It was an all steel, semi-auto, with an 8 round (+1) magazine. Made in France in the post war years it was a beautifully made and well finished gun. Worked like a charm too. Both reliable and accurate. I got no idea why I sold it, and it's one of the few guns I really kick myself for selling.
High-Standard Sentinel revolvers. About the same size as a Smith & Wesson K-frame (fit the same holsters) but was a nine shot, DA/SA revolver, with an alloy frame and semi-fixed sights. Light as a feather. Put it in an Uncle Mikes nylon holster and you had, IMHO, the perfect "bumming around the woods" gun. Plenty accurate enough for pine cones and such. Another of those "I wish I hadn't sold" guns, but I do have this one my wife wanted.
Ithaca's Model 66 and 49.
The 66 was a standard break action single-shot shotgun available in all the standard gauges, except it had a lever rifle type lever for breaking the action. In the day of TV westerns, it was a big thing to a 12-13 year old kid (me). Mine was a 20 gauge.
The Model 49 was a similar 22. It looked like a lever gun, including a false magazine tube, but was actually a falling block single shot (they also made a 49R that was a repeater, but I've never actually seen one). Another great gun for a day and age when nobody thought anything of a kid with a 22 rifle walking down the road.
