Ev.{Ivan Evernden - coachwork}1/JH.23.2.40. Flywheels. In January of this year you asked Hs{Lord Ernest Hives - Chair}/NRO. to tabulate all of the available flywheels for the 6 cyl. alum engine, and the B.60 and B.80 cast iron engines with the R.R. starter motor and the Lucas starter motor. At the same time he was to provide dimensions for a flywheel of the light type for B.80 and a heavy and light type flywheel for the B.60 all for use with the Lucas Starter Motor. During NRO's. illness we were able to collect his figures and we have made the attached charts. In the interim period we have issued designs for the outstanding flywheels for B.60 and B.80 for use with the Lucas starter motor, viz. PL.109 and PL.110 respectively.
