Thank you Kevin and Colin!

If someone can supply me with a 600dpi scan of an original AVO Mk I / II scale I can adapt my scale to fit to the Simpson meters too.

But there will be a need for a meter amplifier anyway as the internal resistance of the AVO Mk I / II meters is much lower than the Simpson 29T (I can't find any other Simpson meter that has the correct FSD and internal resistance either).
