Harley,I'm doing this from memory and a few drawings I made.Under the forarm;name Vittoria on both barrels,#7335 3 on one barrel;proof mark ?? similar to the English crown but with a cross on top and the letters are reversed'ie' PB,and choke-P.Schultz.
Hammers are exposed.
Shotgun is made for white power;Translated from French???.
Vittoria and a winged angel are engraved on the rib,along with' veritable monoblod'.
If the water table is what I think,the proof mark ?? appears there twice.
Stock is a pistol grip.Do not remember the type of engraving.Believe the receiver is case hardened.Double triggers and no auto ejectors.The name P.Berretta and address appears on bottom side of left Barrel.
