Jesus Christ. That is cool. Good find. Very close and that buckskin looks to be a match eh. Longer pointier collars damnit but they do have a very cool natural turn up at the ends.
Yeah the 2-way zipper might mean it’s newer than it looks.
Or! It’s an old jacket that’s just been cut apart and tailored adding the 2way and that’s why those button loops are still hangin there ~ ?
There’s also a bit of a sunburst like detail on the back as well
