Inscribed along edge, CAP OF 15 LB SHELL FIRED BY GERMAN AEROPLANE TSCHOUKAIB G.S.W.A. DEC.1914.In a diary compiled by Cpl Douglas Scott King , of the Kaffrarian Rifles there is a entry dated Thursday, 17 December 1914, which reads: 'A very misty morning - but I'm darned if that confounded aeroplane didn't come again. It dropped two shells near our big guns - both exploded. 4 men hurt - and one killed - no guns damaged. German Airman Tr�ck was believed to be the pilot of the attack of 17 December.The bombs which descended upon Cpl Scott King and his comrades were incredibly effective, in view of their improvised nature. For they consisted of a piece of stove pipe, a spring, and several pieces of wire. To these were attached an artillery shell. The device was released on to its target by tugging at the wire; whereupon the shell zig-zagged a course to the ground and actually exploded.This is the head of one of those shells.Rare piece of early military aviation history
