Hi, I wanted to install an auto rewind unit in my 1921 M. Schulz
player piano.  I had one I had taken off another piano, but the hoses
were undone so I couldn't see where they went.  Mine is a homemade unit
I think, like new and works good, but do not know how it goes on.

It has two smaller tracker bar tubes and one larger one that I assume
goes to the pumping bellows.  So does anyone have any information how
to hook it up, where the hoses go on the tracker bar, etc.?  Pictures
or diagrams would be helpful, too.  Thanks so much!
