Antique Vintage Solid Wood Mason Factory Duck Decoy Black Duck. Looks that way to me. Rough area edge of tail someone put touch up black paint to tone down the bare wood and minor paint loss minor roughness at end of bill. Factory filled crack along back. An inserted small round weight sunk in lower left where flat bottom ends and round side begins.
Overall a very nice example. If choose Parcel Select be aware it's slow and it's not my fault.
Looks like neck filler may have been replaced at some time. This item is in the category "Sporting Goods\Hunting\Vintage Hunting\Duck Decoys".The seller is "rayv53" and is located in this country: US. This item can be shipped to United States.
