Check US websites, apparently its a Thompson or Thomson pump and you can get kits for it under that name. I read it a long time ago so don't have any links. You can "Frankenstein" it as Saint says, I did that to my ABS pump which needed new brushes and one of the brushes needed a new holder. Fashioned one from resin and it worked for about 7 months but the next time it went it was beyond repair. Learned my lesson, having the car off the road twice was worth much more aggravation than the price of replacing it the first time and maybe cutting down on chips and ciggies for a couple of months!
