I take the spent shell, cut off the plastic and knock out the primer. I clean the meat off of end of the beard and plact it in a small jar of salt to dry it up. For the spurs, I cut the leg bones about 3/4" on either side of the spurs, boil them clean, saving the spur covering and bones, dry them out completely and hot glue the spur covering back onto the bone spur. I now take the spurs, thread them on a leather thong, push the ends through the primer hole in the brass and tie a knot. I then take the beard, place it in the brass and fill the brass around it with hot glue. Once everything has cooled off and set, I take an electric metal engraver and scribe the date and location that he came from. into the brass.
I know it sounds like a lot of work, but it can be stretched out over days or weeks at your leisure.
