And what body part did they sell to pay for it?
I think the real question is - "And what part of their brain did they leave behind when they decided to buy it?" :facepalm
This is
NOT the original screen-used large Liberator model. At best, this is a very-well-made
REPLICA, built by a well-known industry professional that
MAY have a very small amount of the original studio model incorporated into it.
If you were given the front deflector off the original large USS Enterprise filming model, and you built your own Enterprise to the same size to go "behind" the original piece you had, would "your" Enterprise be the "original"? No, and this is what's happened here.
Don't get me wrong, it IS a superb model, but as a
REPLICA it's worth about a tenth of what its new owner paid for it. Oops! :$
