There are no official documents explaining the original item this jacket is based off, but it is designed using a 1910-1920 era U.S. Army jacket featuring embossed donut buttons and made from black sateen. It has 3 pockets, which unlike the later USMC denim and WW2 period USMC/USN HBT 3 pocket coverall design utility jacket, features a modified pentagonal pocket used for a pocket watch. In terms of the timing, it is from the first half of WW1 which I have seen an all in one version with similar pocket design and same material used. However I have not seen any black sateen U.S. Army items since then and even personally close collectors and second hand clothing dealers are not familiar making it a particularly rare item. The design of the jacket and sewing specifications are the same as the #1106 3 pocket jacket which was finally remade last year. For this project we are producing an #1106 with an inner pocket. When I think back, in the 90s when I was designing the #1106, there were quite a few black sateen U.S. Army coveralls on my mind. This gives the flavor of American workwear’s early days in the 1910s and 20s which laid the framework for strong American workwear design to follow while staying true to the roots and taste of the #1106 making it even more attractive to come.
