Well yes they are hobby guns. Some us shoot ours maybe not often, but I stll like to know I can. Some use them in cowboy action shooting I sold a gentleman a Hammerless model for such a thing. As to the self defense part while I have much better options if I had to I have a few that would fill the bill. Lastly there are places in the world if you want a gun to defend yourself it might be your only option. All that being said unless it is a nice or rare specimen the cost of getting one fixed probably wouldn't make sense.Are these old break open revolvers from the turn of the century, merely
hobby guns? Just to casually tinker with? Nobody really shoots these things or depends on them for protection, do they?
