Vintage Blue Wing Teal or Scaup Working Duck Decoy

Description

Vintage Working Duck Decoy, I believe it to be a scaupor a blue wing teal, but an argument could be made for another species  difficult for me to tell. Honest working decoy used condition, with some cracks, old repair at neck, etc., see photos for detail. A nice example of a vintage working decoy by an unknown carver.
