Recently acquired a semi aotu handgun from my grandfather. It has "P. Beretta cal 7.55-Brevettata....GARDONE VT 1944" on the left side of the slide. Below this, on the frame there is a "S" by itself.Serial numbers on the right side are 535198 on the slide and frame. Also on the left side of the gun there is what seems to be a German eagle stamped behind the handgrip with a small circle below that.
Just curios about some history and approximate value of this handgun.
