| X20 Expl: Dept: Hs{Lord Ernest Hives - Chair}/Rml/LG. 30th. Dec. 1926. St.{Capt. P. R. Strong} Helens Cable & Rubber Co.,Ltd., SLOUGH. Dear Sirs, ref. THB-WAC. With reference to your letter of the 24th. Your supposition is correct i.e. we require the inner tubes for 33" X 6.75" low pressure tyres fitted with 5" X 21" well base rims. We are not particular that the weight of the inner tube should be exactly 16 lbs. but should like to know what you estimate the weight will be when carried out with your standard section. Before you proceed with the manufacture of these tubes, we should like to know how you propose to treat the question of price. Yours faithfully, | ||
