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?
       Regards,
       Chris Chapman
