re Phantom III Crankcase Breather.

We send you herewith LeC.5067 showing an oil baffle box made as a part of the breather pipe from the crankcase.

The oil collected in the box is drained away back to the crankcase via the oil level gauge.

Will you please put in hand the detailing of these parts forthwith.

To get a quick test of this it is suggested that RHC{R. H. Coverley - Production Engineer} should make a similar oil separator out of sheet metal.
