| FHC. from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} x5090 Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} 6/AD4.11.31. LATEST TYPE CAMSHAFTS. We want to fit our existing China units with new type camshafts E.57177. The one we most urgently require is camshaft in C.9 unit which is at present on the test bed and it is not of much use to us until we can reproduce the power we have got on 18.G.IV. The other China unit at present in 12.G.IV. C.I. unit, will also want a new camshaft as soon as one is available. Summarising the camshaft position we apparently want one for - 20.G.IV, 18.G.IV, 19.G.IV, 12.G.IV (C.I. unit and one for the test bed engine). Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
