I've found only three references to this fly, a recipe in Hardy's*Salmon Fishing, another mention in an article written for Bailey's magazine some time between 1860 and 1910 and a third listing in*The Catalogue of Hardy's Angling Specialties, as a good fly for the Forth and Teith. The fly is called either the Claret Scott or the Claret Jock Scott depending on the publication.
