My wife was cleaning the spare room and came up with these. I made them 50 years ago when I was 18 and into falconry. Never had a bird that they would fit. Stuck together with Pliobond contact cement. The brown one is coming apart. Got the instructions from "North American Falconry and Hunting Hawks" which I also still have, number 372 of 1500 printed. A guy should keep a few things that mean something.
