Carbon brushes for Tellus/Nilfisk GSD/GS80/GS90

I'm looking for carbon brushes for a Tellus/Nilfisk GSD. They are obsolete but a euro website helpfully gives the size as 10mm x 5mm x 33mm, and I'll need sprung ones.

I see no need to replace the whole brush holder assembly it is in very good condition. I would not say no if there was a cheap one around but it is probably not needed.

Pic of the brush holder anyway : )



Also while searching I found this nostalgia item ; )


(GS80 looks more or less the same).

The one I expected to see there was the early 80's earworm "TELLUS when you REALLY want to clean your floors!" but that hasn't made it to youtube yet.
