This delicately-named salmon fly appears only in the text of T.E. Pryce-Tannatt (1914). there are no other flies bearing resemblance to Rosy Dawn by any other classic authors. Rosy Dawn is apparently the only classic British fly of Pryce-Tannatt's design to appear in How to Dress Salmon Flies. He lists a fly called the Red Sandy, however it has no characteristics of the Kelson/Hale/Hardy pattern, so this dressing may also be directly attributed to him.
