It is the largest in the group picture. It’s the first one on the left. The measurements are approximate sizes. It is 15″ long by 7 1/2″ wide and 6 tall. It weighs 30 pounds. The duck looks like a canvasback drake to me. I found these decoys in an old Elkton MD Estate so I assume they are locally made for the Chesapeake Bay region. The paint looks original and is in good condition with paint loss and rust spots. See all of the pictures as they are intended to be used as part of the items desription. I don’t know for sure who painted these or if they are even done by the same maker. After doing a little research on the interweb I think some of the possible makers could be John McKinney, Paul Gibson, John Holly or John Graham. The free listing tool.
