To BY.{R.W. Bailey - Chief Engineer} From Hs.{Lord Ernest Hives - Chair} S.F.C. X.2641 Hs{Lord Ernest Hives - Chair}5/LG9.6.20. X.2641 RE SAFER INSULATION OF PRESS BUTTON STARTER SWITCH. With reference to your memo. BY/Mtn16/P8.6.20 we do not think that the thread will stand up in the piece of ebonite. We feel that sooner or later we shall get cases of the thread failing. We found, if we warm the ebonite up at all, the thread was very easily stripped.
