| Y5005. Expl: Dept: Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}1/LG 7th. Mar. 1929. Messrs. The Dunlop Rubber Co., Fort Dunlop, Erdington, Birmingham. Dear Sirs, For the attention of Mr. Jones. Further to our letter of the 28th.ult, We have now gone into this matter and find that the blocks we require should give 400 lbs. at 0.20" deflection. We find that it is desirable that the rating should be on the plus side and therefore regret that your 350 lbs. at .20" will be too low. Yours faithfully, | ||
