| -2- Kingsbury. 20.11.30. I am enclosing a S.B.A. nut and part of the bolt which has broken. The part belongs to the dynamo drive of the 3½-litre Bentley. It will be seen that the drilling of the hole for the split pin just about cuts the bolt in two. This does not affect us on the 4¼, but will when these bolts and nuts are used.
