You will not find one of these coveted little gems any cheaper than this!! They routinely sell for $650-700 even without the box and never with an extra blade.
This plane was purchased in 1996, in Warren Me, by a now deceased physician. It is pristine and in the original older and lighter colored box. It comes with an extra blade that was purchased at the same time.
Price of $550 shipped is firm. Payment by personal check (preferred) or Zelle.
