| COPY. From:- HENDEE MANUFACTURING COMPANY INDIA(Production 20 HP. with 4-speed box and Front Wheel Brakes)N MOTOCYCLES, 366,368, Euston Road, LONDON, N.W. 5th July, 1922. Messrs. Jackson's IMPERVO, 48, Dover Street, W.1. Dear Sirs, I am pleased to advise you that I was successful in winning the 660 c.c. class in the 200 mile Sidecar Race at Brooklands on the 17th June. I also made a non-stop run in the M.C.C. Inter-Team Trials, our Team consisting of three sidecar outfits. Two of the outfits experiences punctures, whilst I made a clean run and non-stop. As usual all my tyres were treated with Jackson's IMPERVO. During this season I have competed in all the principal events and have met with great success, and on no occasion have I experienced any tyre trouble, thanks to your wonderful preparation. On more than one occasion after an event I have found nails in my tyres. Yours faithfully, (sgd) E.A.BRIDGMAN. | ||
