It looks wonderful.
I have to say, though, that in daily use it wouldn't ever have been that shiny!
A technical question: when you were cleaning up the covers and castings, did you remove the trim and paint behind, or carefully mask it up? I think it looks truly splendid, and probably works as well now as when it was new.
Jolly well done.

PS: When I was very small (1960s) we lived in north London close to a Bakerloo line station. When we had to go on the tube, one of my treats was for mum to let us get in the guard's carriage to watch him working (they used to just put a bar across to separate the operational area from the passengers). He had controls for the train doors and to signal the driver, etc. The buttons were hinged at the top behind the panel and would wobble slightly with the movement of the train. They were also so worn there was a pronounced, thumb-shaped indentation in the most used ones.
The buttons on your Bursgreen reminded me: it's brilliant.
