| S/W. [Handwritten: Y4117 B62] Dan Hanbury, Esq., - 77-A-7. Castle Malwood, Lyndhurst, Hants. H2/H24.2.33. [Stamped: L FEB 24 1933 RECEIVED] Mr. Hanbury called and saw me last night to enquire whether it would be possible to devise and rig up some form of small auxiliary pressure fed petrol tank to assist the Autovac supply at high altitudes on mountain passes. I enquired what led him to think he wanted this and he explained that at high altitudes - especially recently on the Stelvio Pass, which is over 9000 ft, he experienced popping which he could not cure and which forced him to the conclusion that the Autovac supply was inadequate under the conditions maintaining at that height. I told him that I would put the matter to you because, in my view, you would claim to be able to make some suggestion which would get over whatever the trouble is without the need for any such additional apparatus as he was proposing. The matter is of some urgency because Mr. Hanbury is leaving for the Continent in one week from to-day though we are [handwritten: not?] quite sure whether he is taking the car with him. Would you therefore write to him direct and let us have a copy of your letter? H.{Arthur M.
