Per my research, this is a 1970's Landlubber chore coat. Beautiful vintage denim. 100% cotton. Great quality. 5 button closure. However, 4 of the buttons are missing. This leaves you to be creative and replace with buttons of your choice. Pit to pit is 22". Length is 30". Tagged size 40. The seam needs to be resewn on the back upper sleeve. Otherwise, this is an amazing find.
