I am hoping to find someone who owns a National 8-roll changer
nickelodeon who would be willing to send me photos of their piano
or help me if I have questions while I restore the one I recently
got hold of.  If you have one of these instruments and would be
willing to help me, please let me know.

My first question is that mine has a mandolin rail that has
pneumatics which turn it off and on but from information I have
found for the tracker scale it does not seem to have a hole to
operate the mandolin rail so that is a mystery to me.

My contact e-mail is ampicoman@comcast.net.geentroep [delete
