Hanbury - Head Complaints} Dept. [Stamped, struck through] X.8090 BY7/G.13.7.28. VALVE ROCKER BRACKETS - PHANTOM ENGINE. -------------------------------------- With reference to the proposal to change the material of the valve rocker brackets which are at present made in Duralumin to steel, I have been discussing this matter again with the Experimental Dept. and their further experience leads them to the conclusion that we can use the whole of G.2 series brackets in Duralumin and change at the commencement of 'H'. This means that we make the change with very little material scrap. BY.{R.W. Bailey - Chief Engineer} | ||
