would have to work, there does not appear to be any means of
automatically lubricating them: grease gun nipples being relied
on.

The car tried on the road was fitted with a Weymann
body. The height of the roof was about 5 ft. 4 ins. from the
ground. When driven straight at moderate speeds, the suspen-
sion was excellent, all small low speed road shocks being
totally eliminated. In spite of the low weight and low centre
of gravity of the body, there was a definite tendency to roll
when cornering at any speed. This was obviously due to the
lack of lateral control. The suspension was very fair when
running straight at high speeds on bad roads, but would have
been better with a little more damping. Brake power appeared
to be very poor, as was more or less inevitable with no axle
control. The steering (which is an innovation, having two
independent pendulum levers operated separately from the
steering box) seemed very heavy and as far as we could see did
not self-centre (we were not allowed to drive the car), and
developed the most violent low speed wobble during the test.

The rear axle emitted all sorts of strange noises,
amongst others, a pronounced knock emanated therefrom every
time the clutch was let in or the car was accelerated. This,
presumably was due to, in a measure, the winding up of the
rear springs. The engine was hopelessly rough and noisy.
Altogether this car was rather disappointing being in a very
experimental condition. The makers do not appear to have
had time to attempt to overcome its more obvious faults. The
suspension would have been commendable had it not contd :-
