My collection contains a variation tied either by Leisenring or by Pete Hidy that I photographed last spring.
I have come up with my own tentative interpretation of the pattern which is attached here, followed by the two vintage versions.
Leisenring said that the collar hackle should be slightly larger than the the palmered rib, but I have probably exaggerated the size difference. My collar barbs should be shorter, and the barbs of the rib hackle a little longer.
Hook: #12 Grip 14723
Thread: Pearsall's Gossamer Primrose silk
Hackle: Rusty dun hen
Body: Yellow-orange Anchor tapestry wool, single strand, color 8134
Rib 1: Peacock herl
Rib 2: Lagartun oval gold tinsel, small, X-strong
Ribbing hackle: Pale watery dun hen

This one below was tied either by Leisenring or Hidy

The one below was definitely tied by Leisenring in 1941. Unfortunately the hackle barbs match the color of the cloth, so they are very hard to distinguish.

Leisenring's 1941 recipe in ATWF is:
HOOK: 13, 14.
SILK: Orange.
HACKLE: Pure honey dun of rich color and medium stiffness—two turns.
RIB: Fine peacock herl of the sword feather—one of the long, thin fibers.
RIB # 2: Very narrow gold tinsel wound right alongside of the peacock herl rib and in front of it.
RIBBING HACKLE: Pure honey dun hackle slightly smaller than the front hackle.
BODY: Dingy-orange worsted wool.
