I'm still looking for info on these if anyone has resources or suggestions. They're made by Gardner-Richardson of Middleton-Ohio around mid to late 1930s. My internet search turned up some decoy patent documents for decoys, and this:

But there doesn't seem to be much out there. Any advice on how to find out more would be appreciated.
