Chandler}4/MH.{M. Huckerby}11.11.38. FLYWHEELS. B.III UNITS NOS.6 & 7. No.7 Unit for chassis 8.B.V. Please fit the flywheel and clutch now on 8.B.V. (ex. No.5 unit), but with the following difference. Fit heavy inertia ring Rm.{William Robotham - Chief Engineer}535 (already made, J.Eastwood has it) in place of the present light ring Rm.{William Robotham - Chief Engineer}536. (We are anxious to make sure that the flywheel and clutch now on 8.B.V. continues on that chassis, in order to get mileage). Also, drill 4 - .125 oil holes in Rm.{William Robotham - Chief Engineer}535 and Rm.{William Robotham - Chief Engineer}537 as sketch herewith. (These holes are being shown on the drawings). No.6 Unit. Please fit one of the other Rm.{William Robotham - Chief Engineer}533 wheels now being made, with inertia ring Rm.{William Robotham - Chief Engineer}535. Rm{William Robotham - Chief Engineer}/NRC.{N.
