| O.O. From Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} [Handwritten]: K7410 Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}4/MJ.8.10.30. LOW RATING ROAD SPRINGS. X.4429. X.7410. X.5410. Will you please send to Messrs. Firths the weakest pair of rear springs that we have which we understand are 1100 lbs., and get them to alter the free camber to 9.75". Will you also please order from them a pair of rear springs having 12" positive camber and giving a load of 1300 lbs. at 12" deflection. We are also sending into the Stores to be returned to them one pair of 5.5" pos. cambered 1100 lbs. springs at a normal deflection of 4.5" to be altered to 950 lbs. at 4.5" deflection i.e. the poundage to be reduced 150 lbs. We furthermore wish to obtain a pair of 20 HP. rear springs to the following specification.- Free camber 8.00". Pos. Loaded camber - Flat. Max. bump 5.00" Neg. Poundage at loaded camber 820. These springs are urgently required. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} [Handwritten in left margin]: 40/50 -> Fronts | ||
