Thank you Edward53,
from reading numerous posts on OF I had also come to that conclusion myself, leave well enough alone and keep original as much as possible. I posed the original question as I didn’t know if there was something I should be doing to stop any deterioration of the condition of the dial. Aesthetically I have no issue with the condition and don’t mind the few ‘age spots’ that are present.
thank you for addressing the issue of the cost, I think I will ‘shop’ elsewhere for restoration of the movement only to return it to working order. Much appreciated, grateful for your advice.
regards
D
