All joking aside . . . I'm surprised to find out that there are as many out there that do use a section of the bike inner tube. I'm also surprised that someone hasn't started to make a "slip over" in different sizes and colors as they would probably sell well if priced right (i.e. a couple of bucks).
If a pair of '51 Navies were good enough for Billy Hickok, then a single Navy on my right hip is good enough for me . . . besides . . . I'm probably only half as good as he was anyways. Hiram's Rangers Badge #63
