Hs. {Lord Ernest Hives - Chair} 20-HP Resonance Air Silencer. We send you herewith: LeC.3426 - showing a modified crankcase breather. This design has been tried and proves satisfactory for keeping down the oil consumption. Will you please have this instructed for production cars. One point in doubt is the mesh of the gauze for the flame trap. We should like to use 16 mesh, and this is being tested this week-end. The experimental one was 50 mesh.
