Description
The Fuze No. 247 is an “all-ways” action fuze commonly used in a number of British grenades. The Fuze No. 247 Mk I has a body which is closed at one end by a closing cap and has a flash channel at the opposite end. A striker creep spring, cap pellet, and a lead ball are located inside the fuze body. The striker has a concave head, into which the ball fits, and a split striker point.
The creep spring separates the striker and cap pellet. A safety pin is inserted through he fuze body and the striker body, and has a length of fabric tape with a lead weight on the end fastened to its head. A plastic cap fits over the fuze body to hold the tape and weight in place.
The Fuze No. 247 Mk II differs from the Mk I in that it has a single point on the striker, and uses a more powerful detonator, instead of a percussion cap, in the cap pellet. The No. Ill is the same as the No. II, except that the closing cap is cast in one piece with the body, and is closed instead by a plug in its base. Different lengths of tape are used to change the arming times of the fuze.
The Fuzes Mk I and Mk II are obsolete and will not be used for future issues.
The Fuze No. 247 is very sensitive when armed, and should be handled accordingly if encountered in this condition.
