I am still on the hunt for a trap gun and I came across a Beretta Gardone VT O/U S58S Skeet with a 28 inch barrel, it's a 1970ish vintage. I would like to know if both chokes are fixed and how do you tell, also I would like to know what the gun is worth, this gun looks to be in good shape and I will shoot it on wednesday night. Any help on this would be very appreciated.
