As above, working or not will do - just need some inner bits to repair mine!

I have such things, but not in great shape. you want full mirror assembly? I thought they might have been aftermarket ones, but not sure. do you want a photo or something. Will have to dig them out.

Thanks for replying. I went onto the fleabay and got a few similar-looking used motor units (440 and 850) and I think I might be able to swap bits around and get the old one I broke going again, but not sure. I'll drop you a line if I get really flustered, which I will.
