I am looking for some information.  I am looking at buying a 1957 Super 77 Diesel, NF, with hydraulics and wondering what it is worth.  Is there anything particular to look for, injector pump, hydraulic pump, etc?  It has been repainted and is not rusty, but 770 green.  All of the panels/grill are included but not on the tractor.  They are straight except for one but it is not bad.  The front tires are shot and the rear are average.  I have not had a chance to start the tractor, but told it runs.  I was told that it probably needs to be pull started (has sat since last winter).  Does not need to be hauled.  I realize it is tough to give a value but a range would be helpful.  It would not win a beauty contest with the panels off and the wrong color.  It is located in the midwest.

Any thoughts, comments, suggestions would be greatly appreciated.
