re. STEERING.

I examined PN {Mr Northey} 's experimental car. The shocks are the ~~natural ones from catching~~ the side of potholes, and cannot be avoided except by irreversible steering or flexibility in the ball joint of longitudinal steering tube.

Firstly use ~~same opposing non-~~ set up springs for immediate use.

Secondly try other proportions of the set up scheme, say instead of 200 lbs. try 20 lbs set-up in both directions, both at rear end of longitudinal tube.

The geometry is good.
The car has set-up springs in which the set up is too much.
I have written most of this twice as it is important - (send out both sheets.)

R. {Sir Henry Royce}
