| R.R. 385A (100 T) (S.H 159. 11-8-20: G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 7200) X 3579 Hs{Lord Ernest Hives - Chair}2/LG. Autovac Mfg. Co.Ltd., Heaton Norris, Stockport. X 3579 Aug. 22nd. 1921 Dear Sirs, With reference to your letter of the 12th.inst. ref. SR/BC. We have now received the Autovac tanks. We anticipate that the type AV/31 is the one that will be the most suitable for our purpose. We should like to know from you whether the tank AV.31 is fitted with a non-return Valve which you describe in your letter. We notice, that with the tanks you have sent us a spare float assembly. This appears to be a different pattern to the ones which are fitted to the tanks. We should like to know whether this is what you propose to use in the future or what are its' special advantages. We should also like to know what type of Autovac Tank was used when the tests, you describe in your letter, were made. Yours faithfully, | ||
