| To By.{R.W. Bailey - Chief Engineer} X523 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}11/KW.28.8.36. 25/30 HP. Exhaust Manifolds. Replying to By.17/G.26.8.36. We think we should go right ahead with patterns for malleable iron manifolds if these are necessary. From Hancock's experience we are bound to bump into trouble with the existing material.
