1. The grenade has a cylindrical body of thin-gauge steel containing bursting charge of T.N.T. and fitted with a wooden handle which contains a friction-type igniter. The igniter is operated by removing the end cap and pullings a porcelain ring attached to a cord at the end of the handle. The weight of the grenade is approximately 17 oz.

2. The steel body contains a 5-oz. 10-dr. bursting charge of loose T.N.T. in a waxed pa-per container and is closed by a steel closing disc fitted with a detonator pocket. A steel adapter with an internal screw-thread to receive the handle is fitted over the closing disc.

3. The beech handle is hollowed to accommodate the igniter assembly and is fitted with a steel igniter holder at one end. The igniter holder is screw-threaded internally to recei-ve the brass bush on the igniter. The holder is also the means of attaching the handle to the body and for this purpose is provided with an external screw-thread to engage the adapter fitted to the body. A steel sleeve is fitted over the holder to cover the junction between the adapter and holder. The outer end of the handle is fitted with a zinc sleeve in which a screw-thread is formed to receive a zinc closing cap. A retainer consisting of steel and millboard washers attached to a spring by a rivet is carried under the cap.

4. The igniter (Brennzünder 24) consists of a lead tube containing a copper capsule of fricition composition through which the pull wire passes. The upper end of the wire is loo-ped and protrudes. The lower end is coiled to provide the resistance to the pull. A steel tube containing a powder pellet is screwed to the lower end of the lead tube. This pellet provides a delay of 4 1/2 seconds. A brass bush is fitted at the end of the steel tube with a left-handed screw-thread for assembly in the igniter holder. The detonator is of the No. 8 A.S.A. type and is a push fit in this bush. The ends of a length of twine, threa-ded through a porcelain ring, are led through the protruding wire loop and retained by a wooden bead. The twine passes through the handle to an enlarged space at the outer end where the twine and porcelain ring are stowed under the retainer and screwed cap.

5. The handle, with igniter assembly fitted, is packed separately. The detonator is also packed separately. These components are assembled and inserted when required for use.

6. Before throwing, the screwed cap is removed from the handle and the porcelain ring pulled to draw the pull wire through the friction composition. The flash from the compo-sition ignites the delay pellet which burns through and initiates the detonator.
