When I started my collection I couldn't find very much info online when it came to identifing old heads. There are a few sites with pics of great collections like the one our fellow TGer Falk has.
Joining the ABCC will put you in touch with alot of great guys who have the same goal, adding heads to thier collection. The ABCC also has a collection of The Best Of Broadheads that can be purchased. Then there are Wades 3 books. The two on broadheads, old and new and a fish point book.
If you go to my profile and click my home page I have been working on a page with pics of heads I have. Its in the works but there are 130 some heads with most of them labled with names but no ABCC #'s, 20 or so bows and some hunting pics. We still have dial-up and posting all those pics seems to take forever.
I only have about 2900 more broadhead pics to post if I was to cover the ABCC Master List ! ! !Good luck on your collection.
Thanx, Shep
