Found this on the Caithness site (a font of Brit stuff); guessing on the body, though, since I only had the one pic to go by.

hook - Mustad 3906 #6
thread - UTC 140 black
butt/rib - mylar red
body - Ice Dub black
legs - pheasant tail black
wing - deer hair
head - deer hair spun/clipped

Part 1

mash barb; start thread, wrap back part way down bend

tie in mylar, wrap up to point above barb

dub body

rib body

knot up some pheasant and tie it in

clean, stack, measure (gap width past bend) some deer hair; tie in, trim butts
