Hello, I have had these in the back of my shed with some old traps and other bits for years, I believe they are related to hunting / trapping but not exactly sure, can anyone identify them? Thanks for looking the aluminium thing i remember being told held a bird as soem kind of decoy? but I can't remember exactly, and the other metal thing i seem to remember being told something aout badgers but again I don't remember very well.
