Hi,
I think this set of maks has already been answered:
BS 1 stands for Brescia (Italy) and number 1 was assigned to PETRUZZI ANTONIO & BRANCA UGO, changed to PETRUZZI & BRANCA S.n.c. (1971) changed to PETRUZZI 1821 srl (1991) changed to PETRUZZI E BRANCA di Petruzzi Antonio Cesare e C. sas (2010)
They were in business before WW II.
They did use Venice Lion of Saint Mark and crown mark.
