| -2- Though the detail drawings for the 1.6" dia. inlet valves can be made, the making of the valves will necessarily be held up until we have completed further endurance on B-3 as previously stated. This makes the latter very urgent and we should be pleased if you would progress this job as quickly as possible. B-22, which is being assembled for 10,000 miles, to have 3 standard S/SLV inlet valves and 3 valves in S-65. Hs{Lord Ernest Hives - Chair}/L.H.Swindall. | ||
