| 800. RHC.{R. H. Coverley - Production Engineer} from Rm.{William Robotham - Chief Engineer} Rm{William Robotham - Chief Engineer}1/R.1.10.38. B.50 ENGINE. We have now prepared a report on the general result that has been obtained on the new B.50 engine unit including weight analysis, horse-power curves, etc. In order to get a representative picture of every aspect of this unit, we should be very glad if you could let us have some figures as to how much cheaper you think this unit would be on production than the existing Wraith unit. We appreciate that this will have to be somewhat of an approximation, but as a result of all the information we may decide as to what sort of effort is worth making to bring this engine on to production reasonably quickly.
