DESCRIPTION. This fuze is constructed entirely of steel and the unpainted body is de-void of markings. (See fig. 134.) The fuze is formed ot two main portions, the fuze body and the striker mechanism. The body consist of a steel collar, externally threaded to screw into the missile, and a steel housing seated within the collar. A retaining ring, screwed into the upper portion of the steel collar, retains a steel block. The steel block forms a cone shaped seating. A similar seating is formed at the base of the steel hous-ing.

Fitted between the two conical seatings is the striking mechanism, consisting of the stri-ker, striker guide, and detonator cap holder. The striker has a rounded head which sits in the upper conical seating. The striker is drilled to house the two diametrically opposed steel retaining balls.

The striker guide is a sliding fit over the striker and screwed to its basis is the detonator cap holder. The holder is rounded and seats upon the conical seating of the steel hous-ing. Between the striker head and the detonator cap holder is a creep spring.

An arming rod screws into the steel block, passing into the striker and forcing the steel balls outwards. A lug formed on the arming rod, forms an anchorage for a steel wire, 4 1/2 inches long, to the other end of which is attached an arming vane.
