Back in the early 1980's I used information found in "Rebuilding the
Player Piano", by Larry Givens (1963 edition), to get the family's
Lauter-Humana up and running -- and I am somewhat mechanically
challenged!  I can't say how it compares with later books as I haven't
seen them, but it proved to be valuable to me.  A quarter century later
the old instrument still plays as good as ever.
