Hettrick American Field Vintage 40s 50s Duck Hunting Jacket Brown Large? XL?

This jacket has a lot of flaws but is still structurally sound. The individual who hunted in this was good at what they did! There is a lot of staining on the inside lining and some small holes. A couple of the latches on the inside game pocket are missing. There are some small (smaller than a dime) stains on the outside. No holes but there are some small snags at the bottom and on the sleeve. There is some wear to the seam at the bottom of the left side of the jacket. Buttons and zippers functional. Size tag is missing so please consider measurements… Underarm to underarm 23” Length 30” Shoulders 19” from seam to seam Please see photos
