I am trying to find a period correct mainspring vice for the FI. war or the Rev. war, all I can seem to find are civil war or repoductions of ones from fine cased english shotguns, I know its a preaty basic tool, did they change that much ? does any one sell hand forged ones? , I have a period correct ball mold, turn screw, pos. bag, powder horn, Ect... would just like a main spring vice to go with it, also how common was it for a extra lock to be carried in the possible bag as a just in-case item, were spare parts commonly carried? Any imput would be a great help!
