With reference to the attached.

Experiments are in hand to prove how much the output of dynamos can be increased if we make use of the air cooling.

We have already been able to improve our dynamos which we hope will enable us to reduce the size of the dynamo on the Bentley. We shall shortly be running an experimental car with a smaller size dynamo fitted to it.
