the original stem & bar set was likely Ambrosio I-beam

for most Italian cycles in this range at this time one would expect Noli-Cattaneo (Sheffield) pedals but Bozzi seemed to be fond of Way-Assauto and often employed them instead

two plausible hubs would be the Simplex of Italy by Fratelli Brivio and the Campag Sportman
