Naval watercap fuze,
Fuze was manufactured in the Federal arsenals for Naval use. The Navy watercap fuze employed a crooked channel so that the flame would travel faster than the water. The fuze consists of an outer threaded bushing, the fuze is threaded into the bushing, the watercap mechanism is threaded inside the fuze, so there are three sets of threads! Originally covered with a lead pull tab, this was removed before firing. Marked "ORD (symbol of an anchor) / (date)" . Fuze generally intended for large caliber balls, up to 11 inch. Fuze measures: length 2.45in., diameter 1.3in. flange diameter 1.25in. , bushing is 14 threads per in.
