Approximate 36' taper vintage American Casting Association tournament fly line. Multi-taper silk with light taper at fly end, heavier as the spool unwinds. Was used as a Trout Fly Distance or Single Handed Distance Line. Supple and in good shape with original leader material. Estimate in the 6-8wt class. Tapers are expertly joined in the old fashioned way with thin thread. This is a very unique line.
