I have had this entrenching tool in my collection for a good many years and from everything I read it is called the pattern 1908 and it was based upon the ''Sirhand'' tool used by the Indian Army. There was one distinct modification to the P-08 made pre WWI in 1911 the shape of the head was changed slightly and the ''eye'' through which the helve passes decreased in depth. Although in 1923 the entrenching tool was declared obsolete it was introduced again in 1941 and would continue to be used through out the war with one other distinct modification .The end of the helve was fitted with a steel ferrule at the one end during the later years of the war this was allow the spike bayonet from a No.4 rifle to be attached allowing the helve to be used as a mine probe. This particular model is manufacturer marked and dated 1943 I have included an image of a late war modified example with the steel ferrule and a P-37 carry case.
