These are a pair of 501s, late 66 model. Button back stamp is 6, and the back pockets have double stitching. The manufacturing date is faded and mostly unreadable, but I'll note it just in case. There is damage on the thighs and a repair in the crotch. Please refer to the photos for other damage. Recommended for those who want to wear them fitted. Waist: 39cm (laid flat) Rise: 31cm Inseam: 98cm
