Wish I still had the pattern and a picture of "The Gainswell Glory", a dry fly tied specifically to represent a hatchery feed pellet. Gents name, as I recall, was "Well" or "Wells" and the "Gains" came from the "Gains Pet and Livestock Feed Company" that supplied hatchery pellet food at the time for the hatcheries near, where, Well/Wells, lived! (Remember, "Gaines Burgers" for feeding your dog?)
