Coverley - Production Engineer} E/JNR.{Charles L. Jenner}2/HP.3.10.34. re SpectreCodename for Phantom III Front Engine Mounting. We send you herewith:- LeC.4127 showing an alternative front engine mounting which should be fitted to the second chassis and if desired can be fitted to No.1. as it is interchangeable with the present side members and frame packings. This scheme consists of links and silent block bushes and the rubbers are only called upon to take the engine torque. These should be ordered up in soft rubber. This is our early original scheme for the front engine mounting, but was abandoned in favour of the Terraplane arrangement. E/JNR.{Charles L. Jenner} | ||
