Thanks Andy will give them a try.
John,
Went to my local electric repair man first, They are fine on our machines if I source parts, but do not mess around fixing motors etc.
Going to try another.
Could take a trip to Woodbridge in Harlow.
Might try Ashbys last time I asked I only mentioned complete motor but the thought occured to me in the bath that it might be possible to get the various components of the motor. Such as the back .
But ideally i just want two small electric brushes they should cost £2 in old money, when people fixed parts.
