Hi Dick, James , Meredith,
If you can give me the seismic mass and the maximum width of the clamp
strip, we can work out the thickness required quite easily. The wire was
almost certainly a repair.
It is very unlikely to be brass, but it could well be bronze or
phosphor bronze strip. You might also consider a SS replacement?

Chris Chapman
