| 800 By/Jnr.{Charles L. Jenner} from Rm.{William Robotham - Chief Engineer} Rm{William Robotham - Chief Engineer}3/R.1.10.38. B.50. 3.75 bore. If we could have the details of this engine we could get the pattern makers on the job right away. We do not know whether you have produced a piston for it. In case you have not I am asking Swindall to discuss the matter with you, and should be glad if you could produce one which could be put through with the rest of the engine.
