The Companion should be a single shot "folding" shotgun without an exposed hammer. It was probably the least expensive Beretta shotgun made and retailed (at least in the 1970s) for around $150. Most common were 12 gauge and 20 gauge models, but 28s and 410s are around too. This is the same gun as the model FS-1.
