This model, characterized by its highly uneven and rugged denim fabric, general-purpose military donut buttons, iron rivets, and all-yellow stitching, represents the most extreme period of material control in the US domestic industry during World War II due to the war situation. Furthermore, perhaps due to a shortage of skilled workers, the sewing is extremely rough, and the stitch width is not uniform. [Details] Two thicknesses of sewing thread, similar to vintage threads, are used. The main button and inner button are MURAMASA-stamped buttons, and plain iron copper-plated rivets are used. The rivets have brand markings on the back, making this a highly accurate reproduction item.
