I have a clipboard with three heuer dashboard timers. On the top left and right is the AUTO RALLEY timers and in the middle is the MASTER TIME. The auto ralleys appear to match the 1967 - 70 timers and the master time appears to match the earlier 1967 timers. Like I said their are mounted on the top of a clip board with the clips top and left to allow you to time two cars at the same time. It is for sale and I would like an estimate of the value. They are all functioning properly.
