Hi Dave,
The material on that Muddler head was a mixture of Australian opossum, photo’s and monitors tend to distort colors. If I were tying it, I’d go with Paxton’s Buggy Nymph #1 Rust and if anything color wise, I’d err on the brighter more vivid side of the orange-red color spectrum.
While the fibers look thin, the Bird’s Nest in the photos above use teal.
In production we used both dyed barred teal and mallard flank. Teal was used primarily on the Maple Syrup ( a.k.a Original ) and Olive colors where it’s barring would really show off.
By the way, I omitted one more of the old production colors, “Brown and Brown”.
On the Black and Brown ( which is a fairly dark Coachman with deep reds hues ) we tended to go with mallard, so too with the Cream, which would normally be dyed down to semi-lemon wood duck color, although I know some Teal was used at times with the cream.
Also on the original package, the coupling of Natural ( dubbing ) and Maple Syrup ( hackle ) were renamed Regular and Regular in an attempt to defuse consumer confusion. In fact, I still maintain that doing that, created greater confusion amongst the retail and angling communities.
I’ve tossed in another photo containing a set of Cal’s flies, these use a double distribution wrap and make nice emergent caddis patterns. Again, you can play around with the colors to match whatever…
Then there were Cal’s dubbing tools, which were marketed by another firm. Fun to learn and use, but for some it was like trying to master chop sticks.
For fun, I added another photo showing a the bottom of a compacted brick of Teal. Try counting the feather shafts, now imagine how many are tucked up in the down and out of sight. That brick is roughly as tightly bound as baseball and about the same diameter. Another shot of the same brick standing up right.
Another photo of the old Bird’s Nest package ( Brown ) and one of my working bags of lemon wood duck.
For my own use I tie the fly in the traditional method and in a bead head version, using both teal and lemon wood duck.
In places with high volumes of Ryacophila, I often use a peacock thorax and abdomen with a dark greenish olive teal hackle and tail, cooper rib.
Other favorites are Scintilla Dubbing ( #30 Pale Olive Brown ) with lemon wood duck, or Hare-Tron Dubbin’ ( HT4 - Golden Brown ) with wood duck, most commonly with a cooper rib, sometimes a fine gold rib.
Anyway, they’re good no matter which flavor you choose.
Dave
