Chandler}29/JH.26.10.38. Flywheel & Clutch. B.111 & 50. The L.O.P. GB.3793 calls for an 11" clutch, which for some reason was shown on scheme GGD.518. We do not want an 11" clutch on any Bentley, it has 31% extra inertia in the drive plate and costs 13/- more than the 10" which is entirely satisfactory on Bentley. An 11" clutch with flywheel GW.1852 has been fitted to Unit B.111.4, will HPS.{Horace Percy Smith - Experimental Factory Mgr} please change this to flywheel GB.3115 and 10/ clutch, and also fit future Bentley units with 10" clutch pending alteration to the L.O.P.
