| X1525 To R.{Sir Henry Royce} From Hs.{Lord Ernest Hives - Chair} c. to CJ. c. to E.{Mr Elliott - Chief Engineer} c. to BN.{W.O. Bentley / Mr Barrington} c. to Da.{Bernard Day - Chassis Design} Hal/LC9.3.21. X.1525 13-HP HUMBER CAR. The bendix pinion on the Starter Motor of the above car has broken in three pieces. The failure occurred under normal starting conditions. We think the reason this pinion has broken is, firstly, because it is hard right through, secondly, because the section is so small.
