| Hs.{Lord Ernest Hives - Chair} from ROY.{Sir Henry Royce} X20 ROY{Sir Henry Royce}1/MG3.5.27 The St.{Capt. P. R. Strong} Helens Cable & Rubber Co. advise that their Everlastic Tube suitable for our 40/50 HP. standard, i.e. 33 x 6.75" Tyres fitted with 5" x 21" well base rims, weighs 17 lbs, plus the valve 2 3/4 ozs. per each, I think you will find this weight about three times that of the Dunlop standard Tube. I understand we want 2, please requisition. ROY.{Sir Henry Royce} Ry | ||
