12-EX AND NEXT CAR RUNNING IN FRANCE. X. 8940c
CENTRAL OILING SCHEME. X.3806

In examining the first specimen it appeared
to be proving my fears that a scheme so easy to operate
would soon shew itself as unnecessarily smothering the
chassis and [strikethrough]illegible[/strikethrough] engine with oil spray. Also suitable
distribution and reliability to reach every point seems
almost impossible.

This and other reasons have decided us to
make a more practical attempt at centralising the oiling,
and DA.{Bernard Day - Chassis Design} is sending the modifications it is proposed to
make to 12-EX. This scheme consists of the operator being
armed with an Enots oil pump, then connections are brought
together conveniently in the [strikethrough]chassis[/strikethrough] about 3 locations.
It is an easy matter for these to be lubricated say once
a month, in addition to which there are a few isolated
places which could not in any case be oiled while the engine
is running, and these are rendered so oil-retaining that
they only require attention once every 3 or 6 months.

We trust within a few days of receiving DA{Bernard Day - Chassis Design}'s
final instructions that 12-EX car will be completed in
respect to the oiling system.

It will however have to wait for the important
item of the slot induction pipe, and the general improvements
embodied with this modification.
