| R.H.C. c. BY/SS.{S. Smith} c. H.S. X8050 BY9/G.18.7.28. PHANTOM CYLINDER HEAD. ----------- Will you kindly produce a casting from the present turbulent head in cast iron instead of aluminium. We appreciate that the head will have to be treated freely in setting out in order to utilise same, but we think that it would be possible to produce a cast iron head which we could fit to one of the existing engines in order that Hs.{Lord Ernest Hives - Chair} can try out on this head some of the points which are troubling us at present with the aluminium head.
