Real vintage, 1936 Tudor

[Philopous]

This watch turned up in a box of soon to be discarded material from my father in laws estate. It is a Tudor made by the RWC Ltd and given by Mum to Dad in 1936. Lucky I checked the box one more time before I dumped it.
The question is I am looking for someone in the Sydney Area (Australia) that I can trust to have a look at the movement and service it, I would like to pass it on to my son. I would like to pretty much preserve it in its current condition although the face is in pretty poor shape . I gather he wore it as an everyday watch for many years. I will make a decision about the face when I get the movement sorted. If you can suggest someone please let me know.
