This one came with with a lot of issues.  Apart from the general wear from the fact that the Guitar was made in the 70s, the guitar had a major belly bulge, which I corrected using a "bulge buster".  
I also fashioned a new bridge saddle, cut a new nut, fixed the sloppy bridge pins, glued cracks in the neck, glued the top binding, glued the bridge and shimmed and adjust the neck.  then I gave the fret board some tlc with a fret polish a set up and a new set of strings.
the end result was that it was not only now playable with a nice low string action, but actually sounded great too.
