Dear Sir, Re The Isochronous Speedometer. We have seen a Booklet describing your Isochronous Speedometer, and we are distinctly interested in this instrument. We should like to have one of these instruments from you at the earliest possible moment for a trial on our Experimental Car, with a view to, if we consider these entirely satisfactory, possible adoption as standard on our production Cars. We think this speedometer <handwritten>might</handwritten> <strikethrough>would</strikethrough> be a distinct advance on the <strikethrough>original</strikethrough> types of instrument, and we are, as always, anxious to use the best instrument on our cars. We should like to know, if it is possible for you to supply us with one of these in the near future, how soon this could be delivered. On receipt of your answer, we shall be glad to supply all the particulars you require for giving us the correct instrument for the purpose. Yours faithfully, | ||
