| 1305 (Experimental Dept.) Rm{William Robotham - Chief Engineer}/AFM{Anthony F. Martindale}7/R.{Sir Henry Royce} 6th July, 1939. Messrs. E.G. Herbert Ltd., Atlas Works, Chapel Street, Levenshulme, MANCHESTER. (For the attention of C. Norman Fletcher, Esq.) Dear Sirs, Olsen Spring Tester. We are wanting to buy an Olsen spring tester for measuring the rate and poundage of road springs for cars. We use leaf springs up to 1,400 lbs per spring and coil springs up to 1,600 lbs per spring, both being the normal load. There is a 50% poundage increase in the fully compressed position. We believe you are agents for Olsen machines. Will you please send us particulars of their spring testers, and their prices. Yours faithfully, For ROLLS-ROYCE LIMITED. | ||
