This deal made rummage sale pricing look expensive! Not withstanding the guy actually knew what he had and had sold the pintail drakes off and kept what I would call "new old stock" canvasback that was on his mantle, that was a decoy! There was blue bills, a black duck, and a bunch of mallards. The blue bills look really good, plus I doubt they have seen much hunting, some of the mallards show significant usage, this outfit was ahead of their time with the swivel head and relaxed low profile head look.
There was 3 what appears to be some "treadecoy" which I understand were made by the same company, no swivel head and appeared to painted as gadwalls.
BTW if you have any friends with a garage full of Herter's I am always buying LOL at least I usually know what I am dealing with there.
