This is a very fine example of a rare Beretta Model 1918/30 semi-automatic carbine. This series of carbine was actually a modified copy of the Villar Perosa produced submachine gun as designed by Tullio Marengoni, who was the primary designer of all the Beretta submachine guns until the late 1950s. This model can be found in both a full automatic and a semi-automatic version, such as this one and also there were two-clip fed versions; one that fed from the top of the receiver and this one, which is a later, version that feeds from the bottom also. This example uses the standard 25 round bottom feed magazine (which is not included with this gun). This carbine functions as a blow-back operated, closed bolt weapon that has a floating firing pin. This unique weapon is cocked by pulling a small ring on the rear of the receiver, with a small bolt release on the right side of the receiver. The top of the receiver is marked "PIETRO BERETTA - GARDONE VALLE TROMPIA - ITALIA - CAL. 9" lengthwise, with "MADE IN ITALY/BREVETTO 1918-1930/A /4336" at the rear. The underside of the stock has a sliding dust cover over the magazine well with a cross-sliding safety mounted ahead of the trigger. It has a standard blade front sight with a tangent rear sight graduated from 1-5 (100-500) with a barrel mounted folding bayonet. It is fitted with a one-piece walnut stock with a side mounted sling swivel, and a steel buttplate. The butt-trap compartment contains an original two piece cleaning rod. Magazine absent.
