Levi's 82, 515-0217. Now a proper vintage denim, with good color remaining, highly recommended. Also, as you can see in the photos, the crotch area is a bit worn. It's not noticeable when worn. The zipper is a nice 42 Talon. I looked it up, and the predecessor to the 653 was the 16. Also, it's said that old fabrics tend to gather, giving it a vintage feel. Even from this era, they sell for a decent price.
