| X3745 BJ. from BY. {R.W. Bailey - Chief Engineer} c. Hs. {Lord Ernest Hives - Chair} c. EP. {G. Eric Platford - Chief Quality Engineer} c. Hm. {Capt. W. Hallam - Head Repairs} BY4-P22.7.22. SPRINGS 40/50. RE USE OF GAITERS. BJ2/H20722. Whilst we all agree gaiters are most desirable it is considered the full advantage of a constant and fairly low coefficient of friction between springs is only obtained when in addition spring dampers of an easily adjustable type like "Hartfords" are also fitted. The price of £3.15.0. does not include fitting of gaiters. The spring movement dampers considerably improve the action of the brakes and minimise "chunking" in the drive. BY. {R.W.
