G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 643, 19-2-20 G 2616 Contd. -2- Hs{Lord Ernest Hives - Chair}2/LG13. 8. 20. ------------- Hoffmann bearings which we have proved and to try and obtain the nearest samples they can to those bearings. (They have models of every piece on the car) When they have obtained the nearest bearings which can be obtained in America to the models, a complete set of them should be sent over here for approval. Mr. Olley mentions in his memo. that 15 ball bearings form a set. We do not know what this means but it certainly does not mean a complete set of ball bearings for a car. There are 21 different sizes of ball bearings used on the car and as some of the sizes are used in more than one place, there are more like 40 ball bearings to a set.
