wow $200 already, never seen one before (or heard of it) but must be pretty rare. Whats it do?
thought you were talking about brake masters before, woops.
lol it is a twin trip meter for rally cars, especially the mini cos no trip meter was fitted at all
They were a distance measuring instrument used pre=electronics. There was a single reading version....tripmaster, and a twin reading version....twinmaster. You need a T piece to go into the speedo cable and then gears to calibrate it. Find a surveyed 5km distance and run up and down changing gears until you get it right. There were gear charts to rough the calibration in but I bet you can't get them any more. Race and Rally in Sydney were the experts. They were not mini specific, being used in every car. There must be hundreds of them laying around in cupboards.
there is a chart on the net i was reading a few days ago, i just searched halda twin master and got the chart,
