Number 80 Mark VII Fuze

80/44 Number on British fuzes. Time Fuze. Percussion element removed. Introduced 1917. Obsolete 1944.

No. 80 "Time & Percussion" fuze licensed from the German company 'Krupp', was Britain's main WWI shrapnel fuze. This igniferous fuze was set to lengths up to 22 time units before detonating and was also detonated by inertia on impact if that occurred before expiration of the timer. After World War I Britain had to pay Krupp large backdated licensing fees for its wartime use, mostly against Germany.
