Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} re 25-HP. Exhaust Manifold Studs. We should like to alter the material for the four long studs holding the exhaust manifold and induction pipe to the cylinder, to overcome stretching. We suggest that experimentally these should be tried made in Austinetic steel N.M.C. and made plain without any reduction in the stem diameter. The piece numbers are:- E.55581. E.53967.
