Pipe, Also from our area, Parrot shells have been found with Hotchkiss fuzes, Schenkl percussion fuzes , the brass body rare Parrott percussion fuze, the Parrott watercap fuze and I have seen 2- 30 lb'ers with, believe it or not - Schenkl combination fuzes. And I have a watercap fuze from a blown 30 lb'er that the adaptor bushing is brass, not zinc. Come visit !!
