| To RHC.{R. H. Coverley - Production Engineer} X214 Hs{Lord Ernest Hives - Chair}/Smth.25/KW.21.10.35. Hall's Metal Bearings. We have tested the connecting rod assembly at the cold storage works, and find that there is no apparent tightening up of the bearing at -9°C. Will you please not destroy the bit of crankshaft, since we wish to try a solid bearing in a similar manner at a later date. Hs{Lord Ernest Hives - Chair}/Smth. | ||
