Rectangular blue enamelled metal water bottle, enclosed in a khaki wool felt cover secured by webbing straps and fitted with an adjustable canvas shoulder strap. The bottle is closed with a cork stopper attached to the neck by a short string, allowing it to remain tethered when opened. The webbing cover includes a brass button fastening on the front and reinforced stitched edges.
This model corresponds to the British Pattern 1903 water bottle, introduced for the British Army and Commonwealth forces at the start of the 20th century. It replaced the earlier leather-covered types, featuring enamel for durability and wool for insulation. This design remained in service through World War I and into the early interwar period, later adapted in subsequent patterns such as the 1937 issue.
