This is really nit-picking, but "never" may be too strong of a word. According to Michael Sinclair's book on Heddon rods, "... it is believed that some of the 7 foot [series 100] rods were built on a 1F (15/64) ferrule."

They certainly built rods with F sizes less than 1 (with designations like 00, 0 1/2, 0 3/4 and 0), so strictly speaking the poster was correct in saying "a 1F would be a trout rod". Well, yes it would be if they in fact ever built any that size.
