I purchased these 646 Big E jeans from a used clothing store about 10 years ago. They have a 42 TALON zipper. They have been customized into slim pants like the 606. Aside from being a custom item, I think they are quite good vintage denim. Detailed measurements (flat lay): Waist: 41cm Rise: 27cm Inseam: 66.5cm Thigh: 26cm Leg opening: 16.5cm Please note that there may be slight variations due to the measurements being taken by hand. I have included photos of the measurements. Paper patch reads: 646-0517 W31 L34 Please understand that these are vintage items and have been customized.
