All of us are aware that Augustas competed in the Targa Florio, but even Morris was unaware that they had competed in the Mille Miglia until I told him about these pictures.
I learned about Foto Locchi when some friends visited Florence some time ago, but only recently thought about searching their archive for Augusta pictures.
If you go to
https://www.fotolocchi.it/it/archivio/?query=Lancia+Augusta&_=1649691114502 you will find a number of photos - there are two unusual cars (to my eyes anyway) and I wonder whether either have survived.
