An Oilcan Stopper
An empty cartridge shell makes an excellent stopper for an oilcan in case the original stopper becomes lost. The cap in the shell is removed and the hole enlarged with the tang of a file so that a leather thong can be inserted. A knot is tied in the thong on both sides of the base, to prevent the thong from slipping either way. The end of the thong is tied to the bail of the can.
