Beretta’s SO-series over-and-unders are one of the world’s great shotguns. They’re also one of the most influential doubles of the 20th century. Introduced around 1935, the sidelock SO was built by Beretta’s as their answer to Browning’s new Superposeds.
Tullio Marengoni, Beretta’s famous in-house firearms designer, considered Browning’s O/U “..very high, heavy and ugly.” He set about to create an over-and-under that was more like a Boss or Woodward, but that could also be mass produced in a factory like Beretta’s.
Beretta has also made a lot of SO-series shotguns, so finding a decent one is not that hard. What is hard to find is a decent one that has been color case hardened. like the SO-5 you see here. Here’s the seller’s description of the gun:
