Ah yes and the complexities of the Tyrol and its frontiers confused me!
Here we have always called it the Stelvio Pass, and I know the Austrians know it as Stilftserjoch even though it's been Italian for as long as I have known it. In 1934 Bozen (Bolsano) and Trient (Trento) were Austrian, and you would have to approach the Stelvio through Austria unless you started from the top!
Anyway, whatever it was called, it counted to the Italian Championship which Cecchini won.
