In February, 1919, the firm of William Beardmore and Co., of Glasgow, Scotland, in their works magazine, told the story of the evolution and development by them of bullet-proof material for the protection of armored cars, trench shields, armor-plate for the celebrated “tanks,” and other work of a like character. The story, as told by the Beardmore people, in many important particulars runs on all fours with the experiments and results obtained at New Glasgow during the latter weeks of 1914 and the early part of 1915, when a series of exhaustive experiments were carried out at New Glasgow, first in connection with the production and testing of bullet-resisting steel plate. This matter was first brought to the attention of the writer by General Sir Sam Hughes in connection with the shield shovel, of which a good deal was heard during 1915 and 1916. This spade, as supplied by the American makers, was formed with a sharp cutting edge, and a loophole for a rifle, but had no handle. When deliveries began to be made by the American manufacturers, a certain quantity was collected at random and turned over to the writer for testing. This was carried out at the rifle range, of the Fifth Royal Highlanders in the basement of the Bleury Street Armory, Montreal. It was then found that while practically all would stand Mark Six British Service Ammunition, they failed to withstand the much greater impact of Mark Seven Ammunition. Mark Six had a muzzle velocity of about 1,800 feet per second. Further investigation showed that the difference in bullet resisting power in the plates submitted was due to lack of uniformity. No handles had been supplied with the shovels, and no apparent effort had been made by the manufacturers to supply one which was suitable. Scotia’s engineers were asked to meet the difficulty, which they did, and finally offered one which was adopted, weighed eight ounces, and was secured by a single rivet passing through a square slotted hole in the body of the shovel below the base of the tang. At this time the question of supplying our army with armored machine-gun automobile trucks had become a pressing matter. The question had been turned over to a Toronto Committee. Great delay was experienced in securing sufficient suitable bullet-resisting plate, and serious confusion resulted. The experiments in connection with the shovel had thrown great doubt on the efficiency of the steel being supplied by the Americans, and again the Scotia Company were asked to carry out tests and advise as to the matter.
