YOUR REMARKS PLEASE.

Have gear box rattles improved or got worse?
Rattles have rather improved and are not so bad as originally.

Has car been driven all out in spite of engine vibrations? What is your opinion of this vibration - will customers complain?
Yes car has been driven all out there are vibrations but not very bad. Would pass majority of customers but some would find them.

How many times has foot brake been adjusted?
Twice

Has much wear taken place in shackles - are they noisy?
Shackles not worn excessively but rattle badly. The noise is more apparent because of good lubrication.

Have the spring gaiters been oiled - what is the springing like?
Gaiters oiled twice. Springing for this work is too flexible and springs too soft in action. Worse than 59II due to greasy springs and insufficient damping.

What is the car like to ride in - is it free from rattles and engine noises?
Car rolls & lurches too much for fast work, steering bad, same as 59II. Springs & shackles rattle badly, also shock absorbers & joints. Dynamos drive rattles otherwise car not bad for noise.

How is the foot brake for squeaking.
Brakes not squeaking yet but have not run far.

Any trouble with R-W wheels creaking?
Yes all three wheels creak until they have been hammered up very tight and re-tightened after running. Almost afraid of stripping screwed hub by abnormal tightening which seems necessary to prevent creaking.
