Poul said:Pattern from Art Lingren's "Dean R. Journal" (Amato Pub. 2000) is
hook: #2 - 10 low water or dry fly;
body: rear 1/3 red seal fur, front 2/3 black seal fur;
wings: "moose mane splayed at sides with stubs clipped and flared near hook eye"
Designed by Peter McVey, Merritt, BC.
A good friend of mine from Kamloops ties a version with a deer hair wing and a red wool tail instead of the red butt, which works well for him... Not sure if that version originated with McVey or elsewhere.
Kind of a waking version of the old "McLeod Ugly" wet fly.
