British No1 Mk3

The No1Mk3 was essentially the same grenade as the Mk2 except that the top cap was made from sheet brass instead of the complicated cast one of the earlier mk's. This one still has its original markings and whipcord on the pin

the makers mark is stamped onto the wooden block under the streamers.

here it is stripped down to its component parts

here the cap has been removed to show the 2 holding studs that the detonator locks under.
