Stripped my old 25 down (it was my first N gauge engine, second hand some time around 1990ish, 3 pole motor, brass gears), gave it a good clean and after a modicum of jiggery and pokery managed to get it back together and working!!! Go me!!! 

Nice one, Luke
i'll send you mine

Two '47s here that need fixing, what's your address??

All the time I was doing it all I could think was 'I wonder if they still do spares for these'...
There was more of the brushes spread liberally around the inside of the motor than there was left on the brushes! 

And my 91!!!! This sort of confidence can only lead to me breaking my Duchess...
