RARE Vntg 70's LA Machine Paris New York straight leg unhemmed jeans. Size 26

I'm a little stumped by these jeans! They look Very similar to 70's Sergio Valentes but with the LA Machine Paris New York brand ( which I can't find any info on) [ just see the same pair listed on Etsy in a smaller size for $225] These are unhemmed so can be tailored to fit any inseam length. Jeans are meduim wash, straight leg with an 11 inch high rise. Contrasting stitching is a golden yellow. * about 4.5" up from the raw hem there are lines that are faded ( see last photo) other than that they are in excellent vintage condition. There is no material tag. They do have VERY slight stretch but I would imagine they are at least 98% cotton. waist: 26" unfinished inseam: 37" rise: 11"
