Rebuilt from wreck and exported...
FAA's definition of destroyed can range from damaged, damaged beyond repair, or crispy-critter burnt out.
Many warbirds were/are rebuilt from parts of destroyed frames or from composite (sometimes for 3 or 4 frames).
Some composite frames are built up from spare parts and "borrow" a data-plate identity from, yet another frame.

Apparently N56SF was salvaged, rebuilt and exported.
If you really like headaches,
try keeping track of original identities of some (most?) P-51 mustangs that have been restored,..crashed,..rebuilt and rebuilt again, several times... over the years.
Call them Franken-frames (frankenstein).
