Tijack,
Check out ''Art Flick's Stream Side Guide'', still in print. I seem to remember references to the original tied dries, wets, and duns in his book. (been a long time) The Green Drake was famous and one of the first patterns, Royal Coachman, also if my memory serves me.
All the patterns you seek were matching the hatch of British flies on British streams that have no counter part on American trout streams. The streamers and salmon flies were knockouts!
Another book, ''Fishing the Dry Fly As A Living Insect'' by Lenard M.Wright goes into the un-varnished history of fly fishing with chapters like'' The Fly that Fishermen Forgot'', ''Hints of heresy'' and ''killing flies and How to Tie Them''. I remember when his first book hit the stands. People hated him! Ya didn't even mention his name on the trout stream for fear of getting walloped with the butt end of a fly rod!
This reply probably doesn't help much except to bump your post to the top of the pile…..Sorry!
