| COPY. attached 24.4.20 To Wor.{Arthur Wormald - General Works Manager} from CJ. CJ15/E19.4.20. Re Modified Alum: Split Piston. Referring to the attached, I see no objection to preparations being made for the introduction of these pistons, but in the meantime an engine should be kept running day and night to see that there are no ill effects from the alteration. * CJ. attc. copy of R6/G14.4.20.
