The iss wmcd1 is that there is no "wreck" everything that could be used has be lovingly and very carefully repaired, recrafted and made back into the boat.
Whys should Bill and the team be put into a position to build a new boat, and that's what it would be with zero heritage from the original?
I would return the wreck to the Museum , end the conflict while keeping the parts that belong rightfully to the BB Team .
-Mr Smith can go on , re-building new sections to complete a new BB , while the Museum can rebuild the wreck of the BB with their own funds .
-in the end , there would be 2 Blue Birds , but most important , the Museum would not have any rights over the BB owned by the BB Team ,
