I have an electric cylinder mower of about 1982 vintage.

It has pretty well stopped working because the motor brushes have worn out.
Fiddling with the brushes, I can get it to go for a very short time.

I have no idea where to get suitable replacements. Do they come in standard
sizes, so that I could measure them up and get a pair from somewhere?

It is unlikely to be of much help if I mention that it is a Qualcast
Concorde RE35 S, I guess

Any suggestions will be most gratefully received.
