Eric Platford - Chief Quality Engineer} X3527 E8/M16.12.22. 40/50 CHASSIS - OIL LEVEL INDICATOR. X.3527 X.1692 Referring to scheme No.418, Mr. Royce would like you to use a circular glass tube in a slotted brass cover for the indicator portion of the mechanism, arranged so that it is possible to see right through, and with the scale marked on the side. The general idea of the scheme he agrees with, but thinks that a smaller hole could be used for the connection to the crankcase, and that it might be advisable to guide the float and pointer by means of the rod instead of the float. What do the Marmon do with respect to this point, and can you send the Marmon gauge to WW. for inspection, and one of the proposed RR. gauges if there is one made?
