| BY.{R.W. Bailey - Chief Engineer} from Hs.{Lord Ernest Hives - Chair} X196 Hs{Lord Ernest Hives - Chair}2/LG10.4.24. FAN BELTS. None of the Fan Belts we have been testing have equalled the 'Whittle' for reliability. We are sending you the Brammer Belt made by Ramsdens Ltd. Halifax which has completed 4,600 miles. You will see by this the leather is badly cracked and broken in places. We recommend that when you have examined it, it is returned to the makers. Hs.{Lord Ernest Hives - Chair} | ||
