| Hm.{Capt. W. Hallam - Head Repairs} c. Worr c. Hs.{Lord Ernest Hives - Chair} ---- X1360 BY/1/G.2.10.28. CHASSIS GKM-33, WITH CADMIUM PLATED SPRINGS. -------------------------------------------- Your memo Hm{Capt. W. Hallam - Head Repairs}4/W28.9.28. The springs on the above car had been instructed to overcome a fault which the customer complained of in our Demonstration car. The fact that the above springs were cadmium plated must not be used as an excuse for cadmium plating others. My instruction to cadmium plate the springs was wrong in view of the fact that no standardisation sheets had been issued. We shall not cadmium plate any further springs until the standardisation of same has been agreed to. The object in cadmium plating was purely to protect the springs against rusting. BY.{R.W. Bailey - Chief Engineer} BM | ||
