In reviewing our tests of this problem we find that the most promising experiment in hand appears to be that of mounting the shock absorbers on the engine which we now have well forward.

The other test we are particularly anxious to try is that of single point mounting at the rear of the body. Da.{Bernard Day - Chassis Design} has given a sketch of this to By.{R.W. Bailey - Chief Engineer} who has promised to issue the necessary details as soon as possible.
