Thi example was an inert instruct model, and in this pic you can see the inert det group with plastic adapter and the No 6 plastic sttriker mechanism.
Grenade, Hand/Rifle, No.92, Chemical

As the nomenclature implies, this grenade is designed to be used as either a hand or rifle grenade. It consists only of a cylindrical body filled with Lachrymatory Composition, C.A.P. Grade 2 (B2) and two C.E. pellets.

The body of the grenade is of tin plate, cylindrical in shape except near the base where it is coned. The coned portion has a flat base in which is formed formed a charging hole; after charging, the latter is closed by a cup shaped plug which is then soldered into position. The closing arrangement at the top of the grenade is formed to make a pressed screw threaded socket, to which is soldered a cylindrical burster container which intrudes into the grenade body. Into the container fits the bursting charge, consisting of an annular and solid cylindrical C.E. pellet, which are enclosed in a thin paper wrapping togeather with a plastic collar before inserting into the grenade. The burster container is closed by a tin plate fuze holder, with a detonator holder soldered to the base, which screws into the socket and is secured by coating the underside of its flange and external thread with R.D. cement.

The grenade is issued with a striker mechanism No.6, Mark 1, lightly screwed into the socket, and for hand use a Detonator No.99 is inserted and the striker mechanism replaced. The detonator consists of the detonator No.75, Mark 2/1 with the addition of a plastic collar fitted round the safety fuze and secured to the cap chamber by a split ring. For use as a rifle grenade, the striker mechanism is discarded and replaced by a Tail Unit No.2, Mark 1 and adapter, with Fuze No.430, Mark 2. In this case, the grenade is fired by means of the usual Cartridge .303 inch Cordite H, Mark 4.

When prepared for firing by hand, the grenade weighs 10 Ozs. complete and 17 1/2 Ozs. complete for firing from a rifle.

MARKING The body of the grenade is painted grey, with a 1/4 inch red band round the top to denote that the filling is suitable for unrestrirted use. Below this is a 1 inch black band, on which the filling composition code, " B.2 " is stencilled in white. Below this is the number and Mark of grenade and the following legend, all in black.
