Hallo, it looks as if this car was exported to Italy in 2008 and been restored, and is now for auction sale at
https://www.carandclassic.com/auctions/1954-lancia-aurelia-b20-gt-series-iv-g22B0g.
If you look carefully at the documentation it reveals the import from Portugal and the previous registration number of ST-14-25.
Pleasing for me to tie up an "unknown" in my register!
