The inner perforated strap where the buckle is attached to the belt is extremely brittle and needs an oil treatment. Imperial Marine Units in 1914 fought in Tsingtao, Antwerp and Africa. In1915 at Ypres & Africa, in 1916 on the Somme & Africa, in 1917 in Flanders & Africa and during the 1918 offensive in Northern France & Africa.
