Byron,

As I've said before and elsewhere, fy tyers are very innovative. Just look at what items used in other areas have been used in fly tying or the unique methods developed or the imagination of Atlantic Salmon tyers of mid-late 19th century Europe. Having said that my answer to your question is an emphatic YES! Come to think of it, what makes you think that the fly was not developed by someone other then Mr. Troth, prior to, at the same approximate time or after? This in no way takes anything away or diminishes Mr. Troth's innovation and widespread acceptance of his initial pattern.
