RE; CHASSIS NO. 55.GX. & 52.GX. 'N' DEPT. With reference to the dynamos off these two chassis. We found traces of water in the Comm.end of the machine off chassis 52.GX. The bearing also had water in it, and was very rough. The machine off chassis 55.GX. appeared to be O.K., except that the brushes had become noisy. I might add that these brushes are the 'Z' type, and that we frequently have trouble with this class of brush . Morganite brushes seem better in all cases. SFT{Mr Swift}/EJB.
