N.W.10 TELEPHONE WILLESDEN 1270 TELEGRAMS "TOGGLE, HARLES" CABLEGRAMS "TOGGLE, LONDON" CJL/DB{Donald Bastow - Suspensions} Aston Brook Street, Birmingham, 6. Jan. 30th 1936. file Messrs. Rolls Royce Ltd, DERBY. Dear Sirs, For the attention of Mr. Bowering. -------- You will by now have received the pump which I forwarded to you yesterday. You will perhaps observe that the hand control body is of aluminium. Although I do not think that you will experience any trouble with this component, I should recommend you, if possible, to fit the steel body which was attached to the pump which was first fitted to the car. You will notice that I have drilled four tommy bar holes in the knurled screw and I think I can rely on you not to put too much force behind the tommy bar and with this end in view I have supplied a very slender one. If you should require another steel control body, please let me know and I will have one made for you. The blow off pressure of the second pump is about 2100 lbs. Yours faithfully, p.p.
