I am restoring a j stevens 22 crack shot-26 for a friend of mine. looking for some picks of this gun to know how the blueing looked when they were new. And is this considered as a rolling block or a falling block? It looks to be in working order. I have personally magnifluxed the bbl. There are no defects. I was just nosy to find imfo on this gun. Its a fine looking toy. And what brand of ammo would be best to use in it? I know that CCI stingers will be to hot to use. And i was thinking that the supper X winchester might be too hot as well. Thanks in advance.
