CVA used to make a .32 "squirrel rifle" - I had one that was a left handed rifle. I'm not a big fan of CVA as far as rifles but it was a pretty good little shooter. I bought it used down at Friendship and it had a scope on it. It turned out to be a nice shooting little rifle and pretty accurate.
I used to shoot at an informal shoot once a month. One of the guys had a H & A underhammer fitted with a .32 caliber barrel. It was kind of a standing joke as he showed up each month with a powder flask and the rest of his supplies, caps, patches, balls, etc. in a musket cap tin. A lot of kidding but when it came down to the picking of prizes - he was usually first. It was his only gun and gave credence to the old saying . . . "beware of the man who shoots one gun".
You might keep track of what is on gun broker and put a WTB in the classifieds here and see what shows up.
If a pair of '51 Navies were good enough for Billy Hickok, then a single Navy on my right hip is good enough for me . . . besides . . . I'm probably only half as good as he was anyways. Hiram's Rangers Badge #63
