With reference to the extraction nut, it looks as though this ought to screw up to some shoulder, as when screwed on to the hub it is quite tight. The new nut seems a little bit mean. The loc king wire would not be needed as the split pin in the main nut would keep the extraction nut from being loose. There is no reason for the extraction nut to come off.

I feel inclined to agree with you that owing to the restricted room and the number of these levers likely to be made from this date, that it is really worth while altering the design.

I think on the new chassis we should endeavour to fit a convenient means of withdrawing the lever from the shaft. On this old design it might be advisable to leave a simple collar in which a hub drawer could be used. I certainly do not like cutting down the actuating nut and apparently the diameter of the boss.

The screw thread to be put on the lever also would appear to be rather inconvenient, but about this you will let me know; it depends so much upon the machines at the works, that is, whether they can swing the lever.
