MINE SHRAPNEL MARK I, 1943.
Indian ink on tracing paper, 1943.
From a collection of technical drawings of mortars, grenades, bombs, fuzes and weapons produced for training purposes during World War Two.
Possibly drawn by Lionel Gordon Haigh, an industrial chemist who worked in munitions and served in the 11th West Riding Battalion, Home Guard, brother-in-law of the donor.
The collection includes original ink or pencil drawings, but the majority are blueprint or the colour printed versions of them, many of which were issued by West Riding District Grenade Training, Home Guard.
