Herewith we send N.scheme 3431. - Front Expansion Chamber.

It will be seen that we have made the simplest shape possible without baffles or other complications, but it may be desired to try a baffle during the course of the experiments.

It will be noticed that we are asking for a slight modification to the centralised chassis lubrication to the front axle.

The general arrange-ment will follow.
