Used on many trade guns, fowlers and jaegers as well as single-barrel shot- guns. With the double thumbpiece, it is a beautiful, authentic pipe for the builder. The tang is left wide and plain so the builder may taper or shape to fit a certain style of gun he is copying. The ends of the pipe are expanded or raised, then the double wedding bands are installed on the raised portion. Sizes: 5/16", 3/8" and 7/16". Available in Brass, Iron or German Silver. Set shows 1 lower and 2 uppers.
