An old Indian musket came way a while ago. I think it is a wallhanger. The barrel is slightly bulged here and there. The lock spring is not too strong, the base plug has been peened over and the stock is held in place with a woodscrew.
During these quiet times I might file the bulges out of the barrel and re-brown it, clean the lock up and sand and redo the stock. There are no pipes under the barrel for a ramrod so I might make them up and solder them on.
It will keep me occupied when I get bored.
