| 1021 Rm{William Robotham - Chief Engineer}/EAG.S/ET. 8th January, 1941. The Empire Rubber Co., Works Road, LETCHWORTH, Herts. Dear Sirs, We are sending you herewith a piece of sponge rubber taken from one of our cars, on which it is used as door seal. We find that this absorbs water and that, during sharp frost, it gets frozen up. We should be glad to know if you have a similar sponge rubber section which is encased in skin that will prevent absorption of moisture. Yours faithfully, | ||
