Commutator is in moderately good condition, but the trailing edges of the segments are somewhat burnt. The brushes are smooth, but have evidently been disturbed and lost their polish by handling. The wear since being fitted in August last is Positive .041", Negative .052", Control .0535". The mileage covered in this time is not known.
