Correction: I called the automatic tracking device I need for my
upright Gulbransen a "fishing pole" and have been kindly corrected.
What I need is information on how to obtain a "Jigger" and it's
linkage.  A picture is on page 125 item #136 of Player Piano Servicing
and Rebuilding by Arthur Reblitz.  Any help would be great!

Take Care All,
Danny Aden
