Very nicely made example of a two speed hand winch to Dave Lammas' design, serialised in "Model Engineer" and built from Woking Precision castings. Speed is selected by moving gears along the top shaft with the lever, rather like a traction engine gear selector. There is a ratchet and pawl on the main shaft, and a hand operated band brake.
Rather a rare model, I read the articles some years ago but this is the first one I've seen in the metal.
