I have not been able to find out through Google searches, but is it possible to upgrade an oldish 3A arm to have 'Gold springs'?

Yes contact Rob Luna, this is what he does. I'm sure you can find his number on this forum somewhere.

You could also contact Hugo Langer from Steadyrig he rebuilds all 3a arms to better then new .He has also designed fantastic new springs as well.
There are many op's here who use his arms .He also has several demo units in different parts of the world where you may be able try first.
