AFA/LAH ALL COMMUNICATIONS TO BE ADDRESSED TO THE COMPANY. Messrs.Rolls-Royce Ltd., Nightingale Road, Derby. 19th.February 1940. Dear Sirs, We thank you for your letter of the 10th.inst. which refers to Mr.Arrowsmith's visit and discussion on Impulse type Clocks. We note that you intend to keep closer observation on the clocks fitted to your chassis, but we feel that it will not be necessary for you to regulate these as each one of these clocks was carefully regulated and adjusted before being despatched, and if there is any cause for drastic regulations we shall be pleased if you will kindly return any clocks in question for our inspection. With regard to the two clocks left with you, we note that you intend keeping these until such time it is necessary to change over either of this type of clock, it is quite in order and the necessary note covering these clocks will be despatched to you. Regarding the cable modifications, if you will kindly return to us one of the 8 ft. drives which you have we would be pleased to do the modifications, we intend fitting the standard S.M.M.T.key drive fitting. | ||
