Agreed probs not too important for a badge Jon but I've recently been trying to dimension / draw engine parts and it is extremely difficult even working in the original units - allowing for manufacturing tolerances, previous bodging, and 90-odd years of wear - to figure out what the dimensions were intended to be. Without the insight that they were dimensioned in eighths, sixteenths and thirty-seconds you don't stand a chance. Conversancy with imperial units is a distinct asset when working on 1920's / 30's British machinery.
