Dear Sirs, Further to your letter of the 10th February last, we have made up four pairs of Couplings, each pair being constructed in different ways, and we feel confident that better results will be obtained, when you have had an opportunity of putting these under test. We have put identification marks on these so that when we receive your report, we shall be able to tell exactly which method to adopt as standard in the event of our being successful in giving you something better than you are at present obtaining. We again thank you for allowing us to have this further opportunity. Always at your service, We are, Yours faithfully. HERMETIC RUBBER COMPANY LTD. W. C. COCCORE DIRECTOR & MANAGER. | ||
