In 1908, the M1904 haversack was reevaluated and the design slightly changed. The haversack, now designated as the M1908 was slightly smaller than the M1904. Also the two wire hooks on the back were replaced by two spring hooks.
This haversack was produced in 1915 and issued to soldiers during World War I. The outer flap is marked twice with "COLO", and marked once "136" with light artillery, "1" and "B". The inner flap is stamped "Rock Island Arsenal, 1915"
