These wonderful hollow carved decoys are depicted on pages 14 (Fig. 1.2-Flyers) and 20 (Fig. 2.3-Floaters) of Wildfowl Decoys of the Pacific Coast by Miller. At the time, Miller was unable to identify the maker. Current attribution is that of R.A. Hewitt of Vancouver, B.C. They are dated to 1910. Hewitt was a Canadian representative the the migratory bird convention held in Washington, D.C. in 1916. This is the finest example I've seen. More research on this maker is definitely warranted.
