| W/S {Derby Works / Sales} - C. X 260 Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} 3/KW.6.3.36. 4-B-IV. Referring to C.2/C.5.3.36, the only comment we have to offer on the suggestion is that the unit at present in 4-B-IV is completely experimental; therefore before this car can be sold it will have to be fitted with a new unit. We suggest that if the engine out of 4-B-IV was to be put in the new 3 1/2 litre chassis and the engine out of the 3 1/2 litre put in 4-B-IV, it would save allotting a new unit to the smashed up car. We have in the past got a lot of useful information on engine units from the large number of miles run by Lp. {Mr Lappin} Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} | ||
