Henk it's from an old Carisma M40 rtr touring car. I did an event back in 2009/2010 where CML sponsored with around 10 cars for public participation sessions and the motors were installed in them. They were too fast so I changed for silver can 540's for the public to use.
Incidentally it's this very motor that I used in my video when racing my Turbo Optima Mid Special against modern brushless cars.
