Poor. 1st. and 2nd. decidedly noisy as one would associate with unground gears. AXLE FOR SILENCE. Normal (low geared). STEERING. Sticks badly on both locks, more so on near side lock, does not self-centre, and not so agreeable as our own. No joggles felt, no wobbles experienced. Balloon tyres fitted.

ENGINE VIBRATIONS. Very bad at all speeds and one feels them through-out the chassis especially when running engine light at about 1500 revs. IGNITION. Double battery ignition synchronised. No magneto. ENGINE GEARS. Very noisy, sing at most speeds. PISTONS. Slight rumble probably due to their being on the tight side. TAPPETS.
