Hi there Shaun, I just found my parts book and scanned in the details that you need, follow this link....

this seems appropriate...

Mechanical - Capstain & Rope - Mechanical drive from engine crankshaft

Principal of operation
The capstain winch operation is the same as those used in sea going vessels. It consists of a tapered bollard fixed to a brass wheel, the wheel is driven by a worm roller connected via a dog clutch to the engines crank shaft.
When engaged the bollard rotates very slowly in one direction. Then, a thick, 20mm Marlow Braid or braided Polypropylene, rope is rapped around the bollard 3 times. When the loose end of the rope is pulled it causes the rope to tighten on the bollard. The shape and surface of the bollard makes the rope ride upwards towards the thinner end thus tightening the rope automatically. The load can be winched in at a variable speed, or, if the loose side of the rope is released, the load can be relaxed very controllably.

Pros and Cons
The winch, like all mechanical winches, is very strong and ultra reliable. With only the force exerted by one person on the loose end of the rope, a force significantly greater than many an electric winch can be exerted. The winch can operate at full load forever...the operator is the one who will get tired !
Since the rope is rolled on and then off the bollard, the pulling force is always constant and does not decrease as the recovered object comes closer to the winch as in all drum winches.
Your rope length can be as short or as long as you like, there are no limitations.
Being engine driven it cannot be operated if the engine has failed, it does however, have a crank handle attachment and can be operated by hand.
The winch takes a bit of getting used to, but once mastered, it is great to use.
They are very scarce and take up some bumper space on Defender vehicles - on series vehicles they fit in very neatly.

History
They are available for both Series and Defender vehicles - in the UK. They are also available in South Africa, somewhere on the second hand market - expect to pay dearly.
