Greenwich Coupling Height Gauge

This height gauge is designed specifically for the Greenwich coupling at a height of 9mm from the top of the rails. It allows two items of stock to be run up against the gauge. It has recesses for the buffer plate which should just scrape along the surface whilst the loop should also just scrape along the top surface. The advantage of having two recesses back to back is that it allows you to see if either coupling is offset from the centre line. This is available for 4mm scale only.
