| To RHC.{R. H. Coverley - Production Engineer} X212 Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}7/KW.11.7.35. We asked you some time ago to let W. Bell have the complete single plate flywheel and clutch to N. Sch. 4229, to obtain the polar moment of inertia. We should be glad if we could obtain an accurate figure for this as soon as possible. We should also be grateful if you would reassemble the original double plate clutch, G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 81430, and obtain a figure for this also.
