It would appear Marrickville is off the radar. The Perth contact seems to be the best option at the moment (I haven't used him)
Perth based I have a retired gentleman I use, he is reasonably priced and just likes watches - he works on my reps and gens all the same. Happy to give details if you want
He's happy to take mail ins, I have him working on a couple of 1675s now.
thanks for the kind words all. Glad I could help.
