Kamasan B830 size 10. Uni-thread 6/0 black. Few hackle fibres for tail. Body of suede black chenille. White calf tail fibres for the. wing. Indian hen saddle mottled brown hackle. Comment – a fly originating in Wisconsin in 1930s. Very successful. I believe it is still in use today although the black chenille body is now of peacock herl and the tail of golden pheasant tippets. A nice simple fly.
