HOOK: #6-8 low-water. I suggest Partridge SEB (low-water hook with  looped down-eye).
THREAD: black or brown
TAIL: Small, whole, Indian crow breast feather, or red-orange hen neck feather
BODY: flat silver tinsel
HACKLE: red-brown hackle, beard-style
WING: Slender strips of golden pheasant centre tail feather enclosing a  few strands of orange
polar bear fur.
 
Instructions: The sample substitutes the tip of a red golden pheasant body feather for the Indian Crow. The same GP feather can then be used for the beard-style hackle. A few strands of dyed orange elk mane, bucktail, or squirrel could be substituted for the polar bear. I used some elk, & added a tiny bit of orange SLF dubbing under the hackle to make up for the polar bear translucence.

History: Roderick Haig-Brown was an influential author, conservationist, angler, and magistrate who lived and worked in Campbell River BC. He developed this pattern to imitate coho salmon fry, and his writings make frequent reference to its success in fooling sea-run cutthroat, steelhead, coho, etc. The fly is listed on p.28 of "The Fly Patterns of Roderick Haig-Brown" (Portland: Frank Amato).

Here is a far more beautiful example of the Silver Brown from Art Lingren, noted BC angler, fly tyer, angling historian, and author of "The Fly Patterns of British Columbia" (Portland: Frank Amato):
