A Michigan pattern from the late 50's; kind of a quill-bodied Adams, or an Adams-hackled Quill Gordon. Original was tied Catskill-like; I prefer mine with denser hackle. BTW, herefishy had asked me a question about hackling, so I included some pics; please feel free to skip them.
hook - Dai Riki 320 #12
thread - Danville 6/0 black
tail - hackle fibers brown
abdomen - peacock quill stripped
wing - mallard flank
hackle - grizzly/brown
Part 1
Mash down barb, start thread
measure mallard (hook length), tie in at 70% mark
trim butts at an angle, cover with thread; wrap back to point above barb
measure a clump of hackle fibers (shank); tie in, trim butts at wing junction to create a smooth transition
tie in stripped peacock, wrap back to tail
wrap peacock forward to 60% mark, tie off, trim; brush with a little Sally
