| To ROY.{Sir Henry Royce} Copy to EY. Hs.{Lord Ernest Hives - Chair} x308 E/PSN/FS.{F. Steele}1/MN.10.3.36. Air Filter for Carburetter Air Silencers. We have been aware of the expensiveness of the Vokes Air Filter medium used in our air silencers, and, in conjunction with the Expl. Dept., have taken steps to provide an alternative. Our latest Air Silencer design for the Phantom III, to LeC 5000, provides the usual Vokes cleaner, and an alternative of cheaper construction. This latter will be tested by the Expl. Dept., and if the new cleaner proves to be successful it will be incorporated in the 25/30 and Bentley silencers. E/PSN. | ||
