Alongside his name and rank, the identity tag was also engraved with Lieutenant James’ position — “Q.M.”, for quartermaster — his religion, and his regiment.
The soldier was a former Company Sergeant Major in the Argyll Sutherland Highlanders, identified on the tag with the initials A..S.H.
According to the Imperial War Museum, “Military identity tags, usually in metal or compressed fibre, are discs designed to be worn at all times and to record an individual’s identity. The British Army introduced them in 1907.
“They were produced within each unit, and stamped with key information, typically service number, surname and initials, regiment, and sometimes battalion and rank. Religion was also indicated.”
