BACKGROUND: The M39 backpack was introduced on April 18TH 1939 as a replacement for the previously used M34 backpack. The two packs were very similar, but the M34 had integral carrying straps while the M39 was designed for use with the then newly introduced Y-straps. During the war the early M34 and M39 "pony fur" backpacks were found to be too expensive and time consuming to produce which resulted in the production of a wide variety of less expensive canvas construction combat rucksacks and backpacks although both the M34 and M39 packs were manufactured through-out the war in limited quantities.

PHYSICAL DESCRIPTION: An olive drab canvas pack with leather and cowhide fittings, roughly 30cm wide, 38cm tall and 10cm deep, with a fold-over flap that covers its entire front. Full fur coverage to the main flap. Straps to the rear panel are missing. Name is visible.
