Funny Falk. He is correct, however, but just to get an idea what head it might be can be a little more laid back. I agree on his guess as well. Falk knows broadheads.
By the way, there is a series of books published by Wade Philips. Not cheap, but not so bad, that basically will identify nearly anything known, PLUS, the photos are prety much life size so you can lay the broadhead down onto the picture and get a better idea. These are often available on E-Bay. If you are interested in broadheads, I suggest you look into one of these.
It is amazing how many different heads are and were available.
