Hi MMD,  I just wanted to add my two cents on the "fishing pole"
tracker being discussed.  I have a late small Stroud Duo-Art grand
that I am restoring, with all controls in the spoolbox, and it has
a "Brand" fishpole tracking system.  How strange!  The patent dates
shown are up to 1933.  Anyone out there with a similar instrument?
