Sprite S1800 size 8 hook. Uni- thread 6/0 camel. Cock pheasant tail fibres for the tail, wing case and swept back legs. Body is two strands of cream acrylic wool ribbed with one strand of brown embroidery sewing thread. Thorax of one strand of the wool. The nymph is weighted with lead wire. Comment – this fly was deadly and highly rated by all. In fact any pattern where Richard Walker was involved always fished well.
