Turning the cap (winding)

Tail Is an old iron stock, made in The Netherlands around 1880 by a company called "Pannevis" in Oude Kerk aan de IJssel. This was one of the earliest riveted iron sails. Iron sail eventualy replaced virtually all timber sails all over the country. One of the reasons for this was the chronic shortage of good long timbers. This stock originates from Windmill "Landzigt" in Zuid-Bijerland, the Netherlands.

Capstan Wood (white-gum) and steel, 2.2 metre diameter, 14 Jarrah spokes.
Anchor poles 12 x ex Telecom poles, white-gum.
