| To RHC.{R. H. Coverley - Production Engineer} Y 262 Hs{Lord Ernest Hives - Chair}/Wst.18/JH.14.5.36. B-21 Hall's unit. Will you please arrange for the automatic advance governor on the distributor, for the above unit, to be made to suit the ideal advance curve required. A trial governor was made by us and gave the required results, having a 5" coil 14 S.W.G. spring and the weights stopped off to a 10o flywheel angle range. The stop in the trial governor was only a temporary job, will you please see that the stopping on the correct governor is carried out in a manner that will be reliable and definite.
