I have 50 or so new snow goose heads for Skyfly wind socks, will work on any decoy with a Skyfly type knuckle on top, Dive Bomb has them, believe White Rock has that knuckle also. They are sentries, I rigged some as feeders with an other than standard mounting method on mine, worked good. Mounting pins incl, can use screws also.
50.00 for the works.
