| x1129 To RHC.{R. H. Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/Ed.{J. L. Edwards}15/KW.28.5.36. 500 c.c. Rudge Unit. We are sending a cylinder head casting for this unit into the shop, and we should be obliged if you would machine this to SCT-21a, with modifications to SCT-30. We are doing this head ourselves, as it is impossible to obtain a second completed head from Messrs. Rudge Whitworth, this being a special, one off job. Also we are anxious to try the effect of reduced exhaust valve sizes. The drawing SCT-21a is that supplied by Messrs. Rudge Whitworth. Hs{Lord Ernest Hives - Chair}/J.L.Edwards. | ||
