Savoia submachine gun
The "Savoia" submachine gun was one of
several entrants into the Italian Army's SMG trials from 1917 - 1918. It was
almost certainly developed by the Societa Idrovolanti Alta Italia (SIAI),
which operated under the trade name "Savoia" after the aircraft engineer
Umberto Savoia. Like the other entrants to the trials, the Savoia was adapted
from the Villar Perosa. It was beaten out by the Beretta 1918 carbine and
was not adopted. No further details about the Savoia design have surfaced.
