| X4038 HS{Lord Ernest Hives - Chair}/Bm2/LG. 17th. Dec. 1928. Messrs. H.M.Hobson Ltd., 47-55 Acton Vale, London W.3. Dear Sirs, For the attention of Major Searight. We usually electrically tin all the parts in our petrol tank. We do not know what your experience has been with regard to tank units un-tinned; we should like to know whether you have had any difficulties with corrosion. We presume you would have no objection to doing this for us on the tank units. We should like to have your views on this matter. Yours faithfully, | ||
