| Mr G.W.Hancock - Kingsbury. BY {R.W. Bailey - Chief Engineer} /Mtn15/N.31.3.37. Re: 4¼ Litre Bentley Cylinder Head. Referring to your memo of the 9th.inst. relative to the above, we have received a report from Mr Goodall, copy of which we attach hereto. It will be noted that there is a difference of .004 between the new cylinder heads and the one you have examined, which rather indicates the discrepancy is increased as time goes on, due to distortion, and we propose to investigate the possibilities of improving this feature by modifying the heat treatment.
