nothing much , found the badge and button in the same yard , got the g.a.r dance tickets from a friend and the tin type , also the hammer for a rifle was dug by a friend , hope you enjoy it .
I don't think your friend found a rifle hammer. Looks more like a cast iron thingy that was used to prop open double hung windows. A screw goes through the hole at the bottom, the short finger is flipped up under the open window to keep it from dropping. The longer rounded side is the handle to pull it out of the way or to hold while lowering the sash onto the other finger.
