I continue to research and would appreciate your input. The head does come off if you wish. Underside flat and even has a remnant of some paper it must have sat on.
It has a protruding staple at the front perhaps to keep it from floating away. Weighs almost 3 pounds and is about 10 inches at the highest. Wear for the use and age. This item is in the category "Sporting Goods\Hunting\Vintage Hunting\Duck Decoys". The seller is "alwayschoices" and is located in this country: US.
This item can be shipped to United States.
