Huckerby}9.9.37. O.H.C. BENTLEY. We are anxious to reduce the size of the exhaust valve Rs.{Sir Henry Royce's Secretary}203, on the above unit, trying sizes 1.400" dia. and 1.500" dia. We should be glad, therefore, if you would have two sets of valves and seats made up to the above diameters as soon as possible, so that they may be put on test.
