For the attention of Mr. Page. Dear Sirs, In reply to your letter of the 14th inst. reference FEP/HJC we have studied your drawings Nos.3122 and 3123 and consider they are worth making and trying experimentally. Will you therefore please make for us 16 of No.31.22 and 10 off No.3123. We suggest the durometer hardness of the rubber should be in the neighbourhood of 45 - 50. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
