Full Idea
If a ship is renovated without reconstruction of original parts, we happily identify the renovation with the original; if there was a reconstruction without the renovated version, we would identify the reconstruction with the original.
Gist of Idea
A renovation or a reconstruction of an original ship would be accepted, as long as the other one didn't exist
