[Healeys] Generator brushes

[John Harper]

Simon

There were two widths of brushes. The early ones were wide and the later
narrower. They went narrower when the maximum current rating was increased.
I believe that this change was indicated by the change PV5 to PV6.

If my memory serves me correctly the other dimensions did not change.
