My own experience with the rebuild of my special was a disaster with the electronic Smiths speedo (looks period 50/60's) and a sensor from speedo cable drive in the end I gave up with this and fitted a gps sender at the side of the radiator, the rev counter a similar Smiths device is connected to coil and having checked with another instrument seems accurate. Hope this helps.
