| To BY.{R.W. Bailey - Chief Engineer} from E/JNR.{Charles L. Jenner} c. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} - RHC.{R. H. Coverley - Production Engineer} E/JNR.{Charles L. Jenner}2/HP.17.9.34. 25-HP. Rubber Engine Mounting. When the large diameter air silencer is used with the rubber engine mounting, the vibration of the front end of the silencer breaks the rivetting around the flange. To overcome this we have made a triangular bracket which bolts on to the front wiring tube bracket. We send you herewith a drawing - LeC.4098 showing this. Will RHC.{R. H. Coverley - Production Engineer} kindly get this fitted to a car as soon as possible. E/JNR.{Charles L. Jenner} Drawing to BY.{R.W. Bailey - Chief Engineer} Print to RHC.{R. H.
