| SECRET URGENT To BY.{R.W. Bailey - Chief Engineer} Copy to Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} FVC. E/PSN.1/MN.13.9.35. X308 SpectreCodename for Phantom III - Carburetters. ------------------------ We send you herewith LeC 4706 of a modified petrol pipe attachment for the reverse throttle carburetters on the above engine. It is possible with this modified scheme to remove the float chamber needle valve of any carburetter without disturbing the petrol pipe connection to the other carburetters. The needle valve body has also been provided with a locking plate to overcome the difficulty of the banjo turning when the cap nut is being removed. It should be noted that this scheme requires a new float chamber lid{A. J. Lidsey} and a new spectacle plate, and there are no modifications to the carburetter body. E/PSN. Att: LeC 4706.
