Dear Sirs, I thank you for your letter of the 9th. instant, enclosing prints of the Oyston valves, which I am returning to you as requested. This valve is certainly interesting, but it would see to present difficulties in making it suitable for our type of shock absorber. However, I am glad to have had the opportunity of seeing this, and look forward to the drawings that you are sending me in the near future of your suggested rear dampers. Yours sincerely, [Signature] Gordon Armstrong | ||
