This is a fly line not a cast and was made as a labour of love! some time in the 19th century and must have taken hours and hours to make probably during the winter off season period. It is a level line not tapered and seems to be very light in weight. I imagine it was used with a long soft actioned greenheart (or lancewood rod) fishing a very short line. The line is only about 20 feet long either due to wear and tear over the years or because the maker became fed up with the tedious job of plaiting it. I am informed that it was made in the Kendal area.
William Brumfit (1846-1926), a well known River Wharfe fly angler made alot of his own tackle and the following is an extract from his obituary. "His tackle consisted of a rod of many parts...it boasted of a hair line...the making of which Mr. Brumfit used to declare was the most monotonous job he ever undertook."
