I've let this thread go un answered for too long. I have been having computer problems and reply. The first pic is aMissle Spike broadhead. invented by my old friend C.F. Carrol. He was quite a character.tThat is about the third itteration of that head. The next being the Red Fury.
First version had a glue on ferrule.
One picture of the two small game heads is misidentified. Head on the left is the original Hoyt Magnum Blunt. Earl kept a coffee can full of them back in the shop.
As it turned out the blade was too fragile and the second generation addressed that problem.
