RESONANCE EXHAUST SILENCERS We thank you for your C3/C29.6.32. We hope we shall get GBT-24 without much delay because this silencer has been under development for some considerable time, also it should save £2 or £3 per chassis and the Works are holding up material pending a decision. Furthermore, we shall have a car at Brooklands in the early part of next week and the people there will be available to make any alteration to the silencer which may be considered necessary as the result of your tests in London.
