501 manufactured in the 524 factory in September 1987. This is a so-called "Hachi-maru" (80s) 501. The inner tag indicates it's from the late 80s. It has nylon foot buttons. Marked size: W31 L34 Actual size (flat measurement): Waist 38cm, inseam 82cm. The color is light, but it's definitely an "Hachi-maru" color. The damage is shown in the images from the 10th image onwards. The condition is not good, but it can be worn if the crotch is repaired. Thank you. Denim color...
