This product is a rare and vintage black duck decoy with glass eyes, made by the brand Mason in the United States. Known as a very early Mason piece, this antique duck decoy is a unique and collectible item for hunting enthusiasts and collectors alike. Its vintage and rare nature make it a valuable addition to any sporting goods collection.

Every image search that I have done points to this being a Mason duck it has paint Wheeer and a lot of Wheeer on the head and bill. I’m not sure if it has been repainted but very well may have been.
