He also had a Remington model 4 rolling block 22 takedown with octagon barrel. Circa 1900-1905. Forget what he wanted for it. I think about 650. It's in tougher shape. Some rusting on the barrel and rifling has seen a few hundred rabbits but it's in great shape.
You'll like your H-S. I've got the H-S Military model with the exposed hammer and it's functions perfectly too. I use mine for a farm carry around pistol.
I have a extra magazine for the Military model but I don't believe it'll fit your model. I'll check with a expert magazine guy to find out. Avoid the after-market magazines as most don't function.
