Can anyone come up with some historical background on the Montana Buck (or Montana Bucktail). My primary (and usually reliable) source says it's a Clarence Shoff pattern. Enos Bradner (Northwest Angling, 1947) refers to it as the Montana Buck and calls for an upright wing (I've never seen it tied this way). Roy Patrick (Pacific Northwest Fly Patterns) calls it the Montana Bucktail and gives it a down wing, "length of body".
