D E R B Y. Dear Sir, We take this opportunity of sending you one of our Booklets covering the Tungstone Accumulator for car lighting and starting purposes, and have been recommended to bring this to your special notice by Mr. Bowring of your Epsom Training College, who is not only the personal friend of the writers but has shown considerable interest in the Tungstone Batteries. A particular feature for Export purposes is their ability to be sent abroad in a dry state with a first partial charge, so that on arrival of the car at its destination all that is required is for the Battery to be filled with correct acid when it can be used for lighting the car, the starter being used after completion of the charge on the car. We have already submitted a cell to Derby and no doubt you can easily refer to this for further information on this heading. Yours faithfully, TUNGSTONE ACCUMULATOR CO. LTD. [Signature] Director. | ||
