These are US Boy Scout chinos. Vintage, from the 1940s. The only difference is the olive color; the construction is the same as the military chinos of the time. No waistband, double welt pockets, double-stitched seat and outseam, and a button fly front with nut buttons. The flap is only on one side, but the shape is most similar to 1940s USMC chinos. The fabric is also a right-hand twill, so you could say it's a different color of whipcord fabric. An embroidered BSA tag and union ticket are attached on the inside. Flat measurements: W39 L77cm The original raw hem was likely double-hemmed at the time. Lightly used, in excellent condition. us.army metal chino m41 m43 m45 khaki US.NAVY ww2 World War II military
