| Fm/76 300. DR. [REDACTED] c. Rm.{William Robotham - Chief Engineer} [REDACTED] E/JNR.{Charles L. Jenner}5/HP.5.3.37. Phantom III Engine Oil Filler. We send you herewith LeC.5451 showing a new design of oil filler cap to be produced in Mazak No.3. (Zinc alloy base). The object of this design is to supply a cap which can be quickly undone without burning the hands owing to the close proximity of the exhaust manifold. In accordance with the decision agreed upon at the recent Sg.{Arthur F. Sidgreaves - MD} conference, this cap is to be adapted for the 25/30 and Bentley, both for the oil and petrol fillers. E/JNR.{Charles L. Jenner} LeC.5451 herewith. | ||
