Phantom III Oil Level Indicator. RHC {R. H. Coverley - Production Engineer} /TVT. {T. V. Turner} 1/IB.9.12.36. Referring to the expense of producing the present design of float arm assembly, we have made an alternative design on the lines of the Phantom II which consisted of a cork float attached to an aluminium arm. It will be noted that the estimated saving will be 4/6d. Will you please instruct this experimentally. Herewith LeC.5440. E {Mr Elliott - Chief Engineer} /JNR. {Charles L. Jenner} | ||
