| COPY PARIS. To Hm.{Capt. W. Hallam - Head Repairs} Paris, from ROY.{Sir Henry Royce} ROY{Sir Henry Royce}1/MG11.10.30 ---------------- We understand the A.T. Speedometer people of Paris - we do not know their address - were showing at the Salon Radiators which carry air through the water tubes instead of outside and around them, and they claim that by this method much better cooling is obtained. We are not sure if the information we have on the foregoing is correct in all details, but should be glad if you would kindly make full enquiries, and let us have more particulars - if possible an actual section - and any data you can obtain as to the actual increased efficiency obtained by the system in question. The A.T. Company of Paris are not connected in any way with the English firm - hence our writing you direct on the subject. ROY.{Sir Henry Royce} ENCLOSURE No 630 'JUSTSO' | ||
