however, that it is the best quality of bakerlite.

DISTRIBUTOR.

Regarding the distributor, this appears to be distinctly
defective, although simple to look at. There is a jump spark,
X 800 and yet no ventilation, and the metal of the stationary pieces
being brass, would not stand the nitric acid generated.
There is no precaution taken in this distributor to
prevent the backfire before mentioned.

GENERAL.

We are pleased to see, however, that the style of work-
manship, and manufacture is not of the cheap and nasty order so
prevalent in American automobile construction.
Regarding the cost, it would be hopeless for us to make
the difference in the cost by altering the design between our
coil and the whole of the Bosch equipment. It would be as well
to lay these two out side-by-side, and ascertain the difference in
cost (if you like, by the criticisms of the Works Committee, but
preferably by someone like Mr. Wormald) whether under equal
manufacturing conditions, there should be such a discrepancy of
cost between the complete Bosch electrical ignition system at
£3.17.6 and our coil at £4.10.0. The experts would say whether
it is a question of -
(1) Design
(2) Manufacturing conditions,
(3) Accountancy
(4) Establishment charges,
(5) or the rate of wages in England.

As I have before remarked, it is absolutely necessary
for us to get hold of a reasonably inexpensive source of mouldings
of bakerlite, and ebonite, otherwise we cannot hope ever to be
capable of manufacturing at a reasonable rate. My advice is
(Contd.)
