Dubbn,
I am so glad you started this thread. Roger Fogg's book, WET FLY TYING AND FISHING, (Crowood, 2009), in the chapter "Soft-Hackled Flies (North-Country Flies, or 'Spiders'), on p. 130 has an excellent passage on this ancient lineage of closely related flies, including photos of the Coch-y-bondhu, Red Tag, and Treacle Parkin. The Treacle Parkin has a tag of yellow wool, but otherwise is identical to the Red Tag.
Fogg says that this clan of beetle imitations have names that include Bracken Clock (clock is an old North Country name for beetle), Marlow Buzz, Hazel Fly, Shorn Fly, and Red Clock. Ronalds' version of the Marlow Buzz combined a single strand of black-dyed ostrich herl with the peacock herl. Mike Harding shows variants with hackles of snipe, and the orange/peach-colored feather from the neck of a cock pheasant.
Leisenring's Brown Hackle is like the Coch-y-bondhu recipe published by Fogg, including the natural bronze herl, except that he uses claret instead of brown silk, and continues the gold tinsel tag as a rib. The Welsh term Coch-y-bondhu, according to Fogg, means a red furnace hen feather, with a dark list—which is what Leisenring's recipe calls for too. Leisenring said this was one of his most relied-upon flies. Fogg siad it is the secret weapon for times when the fishing is slow.
It looks like such a simple fly to tie, but I'm finding it devilishly difficult to get the spacing right on either side of the hackle. I am using too many wraps of thread to secure the herl and tinsel at the hackle (3 wraps each), but having had the tinsel escape once, I am skittish about using two wraps only. Must be doing something wrong. I also am driven to distraction by the tinsel that is silver on one side and gold on the other. I keep getting the silver side uppermost, when it is the gold I want.
Here is my tie:
Hook: 14 Kamasan B440 dry fly
Thread: Pearsalls Claret
Hackle: red furnace
Rib: gold tinsel
Body: Three strands natural bronze peacock herl (Thanks Mataura Mayfly!!)
You can see that I built up the thorax with a few extra turns of the herl rope.
This tie is still not what I want to achieve, but it's a lot better than the first ten tries.
