This decoy by Leonard Pryor (1876-1967) of Chesapeake City, MD, is what Evans McKinney called Pryor's Type 2--that is to say that this model has the neck shelf under the head and a broader (less sleek) body.  See McKinney's book (Decoys of the Susquehanna Flats and Their Makers) for pictures of both Type 1 and Type 2 Pryor decoys. This particular example is from the large rig of John Schaeffer (also of Chesapeake City) and has been repainted by Severn Hall who was the caretaker for Schaeffer's rig. The decoy was probably made in the 1920's and repainted in the 1930's.
