Dear Sirs, We thank you for your letter of the 9th. inst. You will appreciate that we are very much concerned about the behaviour of your speedometers with temperature variation as the inaccuracy is so very large. We suggest therefore that you expedite delivery of your improved instrument because we feel bound to point out that we shall have to seriously consider changing our source of supply unless the error is rectified. Yours faithfully, | ||
