From the estate sale of an engineer who worked at McDonnell Douglas and later Boeing.
We think this was given to employees of the program as this seems to be more of a mock up as opposed to a model or kit.
Some paint loss and feels like wood as opposed to plastic.
Sits atop two small metal posts that fit into the underneath of the plane. Pulls apart for easy storage or movement. The fin underneath is metal and that can be unscrewed from the base bottom.
Will ship (very carefully) probably box in a box style as airplane is in one piece.
This is a professionally done mock up.
Will ship USPS with tracking to winning buyer.
