Here are pictures of a Beretta S.55 O/U shotgun made in Argentina.  It was made in 1971 and assembled using components from both Italy and Argentina.  The receiver is stamped with both  Argentine and Italian markings. The Barrels look to be made in Italy.  I'm not sure where the wood came from but I am guessing Italy since the butt pad says Made in Italy.  There are 3 pages of pictures.  Enjoy the pictures and take a look at the comparison pictures I have on the shotgun page!!
