This is a 501, pre-66 model! Original vintage! Single back pocket, small "e"! I think it needs some repairs, but the fading is really nice. Actual measurements: Waist: 38.5 cm Rise: 28 cm Inseam: 77 cm Leg opening: 20.5 cm Total length: 104 cm There are a few areas of damage, but the fabric doesn't feel weak! This is a used item! Please understand this before purchasing!
