Is there a site for identifying old salmon fly hooks? I just bought some down eye single and up eye double hooks [4/0] but I dont know their origin.Thanks,and hey,great site!

Not as far that I know, but I got a book with pretty much old hooks on picture.
"Flytying for salmon" written by Eric Taverner, try to find that one or scan the hooks and send me the pics and I shall try find out!
