| JOHN SUMMERS & SONS, LIMITED, SHOTTON, CONTINUANCE NO. 1. W.A. Robotham Esq. 22.3.39. about 25% of the Bentley, will give approximately the same performance, and will cost considerably less to maintain. You have got an exaggerated idea of the mileage of my motor, which is just over 40,000. It has, I believe, had two sets of main bearings, one set of pistons, and two new back springs. Yours, Richard. | ||
