Hello, I have been left a Pietro Berretta model 71 stamped 1958 it is in very nice condition.I took it to a couple of dealers to ask about it and one said he would offer me $75.00 the other offer was $65.00,then a man who was in the gun store met me outside and told me I should do more checking on the gun ,he told me this is the first year production of this gun and that he would not be surprised to find out it is worth more than what I was told .I have been searching on the net and found this site and I am hoping someone can help me.This is a 22LR,serial #00907 and stamped 1958.Any info would be appreciated greatly,Thank You, Gary
