After seeing what's in the kit you ordered compare what you have to Al Campbell's reconmendations from the menu on the main page. With a set of materials from fifty years ago I would imagine you will not have very good hackle as that was much harder to come by than it is now. Check out the starter set of half a grizzly and half a brown neck from Conranch Hackles (that's Denny) for dry fly hackle. Talk to friends and family who hunt if you don't hunt yourself for duck flank feathers,CDC, and wings, squirrel tails and a patch of squirrel hair for nymph dubbing. deer hair,bucktail and complete skins from any upland birds. Go to the craft store for 2mm foam, goose biots,peacock herl and glass beads. You don't have to spend a fortune to tie flies tho we almost all do.
