Sorry for the delay in replying - I'm busy buying a house at the moment - trying to find one with a decent workshop solution isn't easy. It seems that "normal" people think a single garage is reasonable...

I think the existing part is more or less toast - the gouges are a bit deep

If I didn't know any better, I'd like to suggest that the brushes might have been replaced with a narrower set...it looks like the set in there have really dug into the commutator, because they are narrow and only in contact with about 40% of it! Are you seeing what I'm seeing?
Cheers

I thought the brushes were a bit narrow too when I took it to bits. The holders do look like they should be there though...
The only identifying mark on the plastic holders I can find is a "VR14" - I've done an internet search but haven't come up trumps just yet.
