Dear Sirs, We thank you for your letter of the 9th. June. We have now fitted the new switch with satisfactory results. With regard to the single unit set, we note that it is progressing favourably, and will be pleased to see this set when it is ready. We note you have included a variable tone control in the new model, which we feel, will add to its attraction. As soon as you have a puka unit available we shall be pleased to test it on one of our cars. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
