Will you please arrange that the governor for the above unit to be made to suit the ideal advance line as carried out on a governor which we had from you for trial. This gave the required results, having a 5 coil 14 S.W.G. spring and the weights stopped off to a 10° flywheel angle range. The stop in the trial governor was only a temporary job, though serving its purpose for trial. Will you please see that the stopping on the correct governor is carried out in a manner that will be reliable and definite. Hs {Lord Ernest Hives - Chair} /L.H.Swindall. | ||
