Thanks for your comments guys, I was looking for something different and it seems I got that bit right at least.

Rob & Steve, it is a Steam Engine's wheels, the engine's lifted up on a stand and the wheels are turned very slowly, powered by electricity. This was a 1 second exposure, handheld but resting on a perspex fence put there to stop fingers getting in the gubbins.

It was lit by a couple of lamps and liberally oiled which is why it gleams so much. The odd angle is to crop out some trays which were catching the oil.
