So I know that I can always mold and cast my own but I am trying to save the time and expense if I can get away with it. The head is a mallard/wigeon hybrid, in the center position in the photos. I placed it between a mallard/pintail head, which is the size of a normal mallard, and a eurasian wigeon for reference. The question I have is what commercially availabe head is going to be the closest match?....the overall length is 3 7/8", I was thinking a drake gadwall might do the trick but I don't have one on hand for size comparison, let me know what you would do. Thanks for your time and help.
