By/EM. from Hs{Lord Ernest Hives - Chair}/Lid.{A. J. Lidsey} c. to RHC.{R. H. Coverley - Production Engineer} 8139^2 Hs{Lord Ernest Hives - Chair}/Lid.{A. J. Lidsey}8/KT.1.1.32. PARKERNISED EXHAUST PIPES. With reference to BY/EM4/J.17.12.31. we are not thoroughly acquainted with the two processes known as Parkerising and Cosletizing, but we believe that the ultimate effect as far as obtaining anti-corrosive properties are concerned, is the same in each case. If this is correct it seems that we must use the cosletizing process for all the silencers that the Repair Dept. will require to replace silencers which have corroded on customers cars. It will be remembered that the Repair Dept. have been instructed to replace corroded silencers by silencers that have been treated, it is only by doing this that we can obtain any reliable data, as our own experimental cars are never driven under the conditions which we know produces silencer corrosion.
