| X4553 Hs. {Lord Ernest Hives - Chair} from BY. {R.W. Bailey - Chief Engineer} BY7-P27.9.22. RECEIVED 40/50 FAN. X.4551 The belts which I handed you today were produced by the Dermatine Company - it is questionable whether they will be any better than the Dunlop, but I think they are worth trying out in order to find the relative life of the belts, as supplied by the two different concerns. There is also probably a difference in the two materials from which the four Dermatine belts have been made, from the point of view of durability. BY. {R.W. Bailey - Chief Engineer} By | ||
