| 4457 Hs{Lord Ernest Hives - Chair}/Rml/LG. 2nd. Sept. 1925. The Cambridge Instrument Co., Cambridge, England. Dear Sirs, For the attention of - Collins Esq. An occasion has recently arisen as to the relative accuracy of the dynamical balance of low pressure tyres. We are anxious to obtain a test on a pair of rear wheels fitted with these tyres. We understand that you have made instruments for dynamical balancing for various Automobile Firms. We should be interested to know whether you could undertake to test these wheels for us on one of your machines and supply us with the results? If you are in a position to do this we should like to know what the cost of this would be. Thanking you in anticipation. Yours faithfully, | ||
