Dynamos for the
Rationalised Range.

There are three potential machines available: Lucas 4½", Lucas 5", and R.R. 5".

We think that we should carry on with testing all three machines.

It seems doubtful if the 4½" machine would be big enough for anything larger than the 4-cylinder cars.

Judging by our experience on the Bentley and Wraith the latest R.R. improved 72-slot armature 5" machine should cater for any conditions which are likely to arise.

Two essentials to enable the machine to cope with the job:-

(1) The use of S.A.E. 20 oil.

(2) The use of 48 watt. headlamp bulbs.
