501 custom made in the USA. I purchased these from a used clothing store about 3 years ago. They have a unique pocket design; I've never seen anything like it, and I don't think it's something you could easily replicate. If you like the design, please consider them. Button back stamp 653, size W36, L29. Actual measurements are as follows: Waist: 41 cm Rise: 29 cm Inseam: 69 cm Thigh: 28 cm Leg opening: 16 cm Please understand that these are used items and measurements are approximate. Thank you.
