<html> <body> Dave, Yes, as I recall there are two zinc string rests in some pianos.  One under the capo, and one as the counter bearing.  They are unpainted metal, but are not as shiny as the usual chrome rear aliquot bars.

Is it also on the bottom of the V bar instead of the rod?   I used protech VERY liberally, more so than I would usually want to admit, and no, the strings are not rusty.     How about that "chrome plated" duplex-like bridge just forward of the tuning pins. This thing looks like trouble to me.   Thanks for the responses, everyone.   Dave Bunch </blockquote></body> </html>
