This could be any taut -band meter, but I'm including the model number of the item of test gear that I've taken it out of.

I understand that this is a fairly well known fault on the RTS2, as if one does not take care with switch-settings, the needle can make some fairly erratic & violent excursions!
So, the coil is o.k. it's a 100uA movement. However the taut-band has broken in the middle, so there's no chance of re-soldering at one end, which can sometimes be achieved.
My question is, does anyone know what the band is made from, it's obviously non-ferrous, and is flat & springy.

It looks as if I could repair it, given that I could find the correct material for the band. I guess I only need about 50mm, that would allow for holding it at each end while I solder it to the tension springs.
Any ideas gratefully received,

Thanks,
David.
