I did polish it, got rid of most of the white crusty and it is nice and shiny but very pale in colour compared to the centre cap, it will do for now.
I have built a battery pack for it and tuned up the radio and got them both on the same frequency and it works amazing. I am very impressed with how well it works for 1939. I do have a bit of a mechanical issue in the stepper mechanism as it jams up every one in a while. I will keep plugging away at it.
