70s leather trench style coat

Dav Martin genuine leather coat. It’s a bit heavier since it is all leather. Lined on the inside. Great condition but there is a couple of dark spots in the back and front (shown in pictures). It has 2 extra buttons on the inside as well. The tag is labeled a 7/8, but it is vintage sizing. This fit me as a size small but a bit snug (couldn’t wear heavy clothing underneath). Below are the approx measurements: S to S: 15 in Waist: 13 in Sleeve length: 21 in Length: 42 in
