OVP 1918
The Carabinetta Automatica O.V.P was a submachine gun developed in Italy for service during World War I. == Development == At the end of 1916, Major Bethel-Abiel Revelli, designer of the Villar Perosa, demonstrated a new weapon to the Department of Air Artillery which was called the Carabinetta Automatica O.V.P. The weapon was an attempt to adapt the Villar Perosa into a single-barreled, shoulder-fired carbine, on the request of the Aviation Corps who wanted a replacement for the Mauser C96 as a personal defence weapon for aviators. The OVP was little more than the barrel and action of the VP attached to a wooden buttstock and provided with a trigger and some small refinements.
