Often referred to as the M35 or M37, neither of these is actually true! The army changed its specifications systems in 1937, but actually retained the same specs. The jumper, or to give its full name, 'Jumper, Working, Denim, Blue' was the direct descendent of the WW1 era brown denim jumpers and was introduced in 1919. This same pattern would remain in use with the army until its short-term replacement with the M40 denim coverall, and after that HBT fatigue-wear.
This pattern was pretty much standard issue for any chore or dirty work, and was issue extensively to the Civilian Conservation Corps in the mid-late 1930s. However, the pattern was not well liked, with many of them being ripped or altered down the front to create a jacket closure. They were also issued to German and Italian prisoners of war who would be given a wide variety of ww1-1930s clothing that at the time were considered to be surplus! If you look very closely on the back of this one, you'll see a faintly marked P that was put on there to ensure the prisoner who wore this was clearly identifiable.
Condition
This example, likely from the 1930s, is in perfect worn vintage condition. This has clearly been extensively washed, certainly with bleach at some point and has washed to a distinct bright blue. The denim, despite that is in excellent condition, there are no tears or rips to the fabric. The buttons are original zinc and all present and correct. The piece displays exceptional 1930s construction including the double needle chain stitched felled seams. The remnants of the stitching from a size tag can be seen in collar.
