There are two new files in the Piano Owner's Guide to Repair - if the black keys on your piano are looking worse for wear, you'll want to investigate "Restoring your Black Keys."

The other file describes the installation of the Universal Bass String - these are strings that are used to first, replace the broken bass string in the piano.  It can be used as a temporary solution until a custom built replacement string can be ordered and installed. 

On very rare occasions is it feasible to replace or restore ivory key tops to a piano - the report below goes through considerations and what it takes for this big job -
