Wow that' a lot of different atlats.
I once sent david morningstar a box of cock pheasant feet.
On the grounds that if mounted correctly, you could use the spur to nock the spear and still keep the claws as decoration.
I don't think he ever used them, but it was a fun thing to send through the post

And in the shooting season I do remove a lot of feet from a lot of dead phaesants.
