Yep, like pete says, its an on car balancer. Press a button and a motor kicks that spindle at the bottom over to spin the wheel, then t'other bit sits against the wheel and reads the vibration on it, which comes up on a dial on the main machine. The big blue bit is a light, but the bulb is blown in it I think. I've also got the adaptor cable to power it with - the machine has a really weird sort of plug I've never seen before. I don't know if its still calibrated - its been sitting under a tarp ever since I can remember - at least 15 years, probably more. As to what its worth - no idea. Make an offer if you want it!
