Thank you for your kind words gentlemen, and the timely reminder from Kalee20 about not leaving sets unattended.
I'll keep an eye on the transformer, although there is evidence of some wax seepage, it appears not to be recent. After a few hours of running, it's mildly warm to the touch.
Below, there should be a PDF scan of the dial glass, which may be useful should anyone wish to reproduce. It's not perfectly clean, as I feared any cleaning would remove the text, luckily, it hasn't and I didn't want to push my luck
Printing the attached onto A4 acetate(?) should produce a fair result.
