20" (double barrel)
The Overland was manufactured between 1978 to 1994 by Rossi in Brazil. It was available in several calibers, with 12 Gauge being the most common.
With its short double side-by-side barrels, exposed hammers, and dual triggers, the Overland is a style of shotgun known as a "coach gun", named as such
because (supposedly) stage coach drivers in the old west preferred shotguns of this type.
