With reference to E1/M14.3.24. You state that the only EAC. engine we have yet tried in a chassis was one that was designed to go in an underframe. We should like to point out that the car which PN.{Mr Northey} ran in France, had the correct crankcase and engine fixing. The only variation from the LcC. design is that we retained the present tubular front cross member and added a pressed steel member to carry the front point of the engine mounting.
With regard to the retard vibrations complained of, they were equally as bad on PN{Mr Northey}'s car as on the original car with the temporary engine mounting.
Hs.{Lord Ernest Hives - Chair}
