| X1180 Hs{Lord Ernest Hives - Chair}/AFM.{Anthony F. Martindale}11/MA. 12th August, 1936. J.N.Longley, Esq., Chief Chemist, Messrs.Ferodo, Ltd., Chapel-en-le-Frith. Dear Mr.Longley, Further to my telephone call this morning about the low coefficient of friction F.B.A. type lining with zinc bonding. Will you supply us with 16 (sixteen) pieces of this material made to each of the following drawings :- G.56921 G.55006 G.54541 G.54542 The above will be enough for four 20/25 HP. cars. We should like to know the number of this material, and if it should appear to be better for squeaks we can use it for Bentley also, increasing the servo output by a change of cam angle to compensate for the decrease of braking. Yours very truly, | ||
