The Black Palmer from The Art of Angling by William Blacker. The one above is tied in hand on a vintage blind-eye hook, while the three below all are tied for fishing on Ahrex FW580 #10.
Another of the palmered patterns from Blacker that can be fished both dried and sub-surface. Simple, but giving a good amount of movmenent and profile in the water
