| X.3426 BY c. to Hs.{Lord Ernest Hives - Chair} c. to E.{Mr Elliott - Chief Engineer} EP{G. Eric Platford - Chief Quality Engineer}1/H12.1.23. OIL LEVEL ON GEARBOXES. X.3426. X.3527 Springfield have adopted a filler plug and oil level gauge as standard on the gear box of the 40/50 car made at Springfield, which OY, has promised to submit to R.{Sir Henry Royce} and CJ. as per latest arrangement. I thought the idea was good and attach herewith prints giving particulars of the gauge referred to. I suggest that the scheme be considered for use on our present car; an easy means of filling and a correct level of oil being important features, so far as gear boxes having correct attention whilst in service are concerned.
