Vintage 50s/60s American Field Men's Made in USA MCM Brown Canvas Hunting Vest

The vest is pre-owned and has some light cosmetic dirt spots from use (hard to show on camera), but it's still in good condition without any rips or holes. The back pouch is made from a stiffer material than the rest of the vest. It doesn't have a size tag, but measures approx 20 inches pit to pit and 25 inches length). Please look at all of the photos and ask any questions before buying. Thank you!
