Inspired by multiple real-life weapons including the LeMat, Kerr's patent revolver, and the Henrion, Dassy & Heuschen revolver, this weapon has two main barrels for firing regular bullets and an additional barrel (operated by the forward trigger) for firing flares, shotgun shells, or whatever else might fit into it.  At 1544 faces (or 2594 triangles), it should fit nicely into any steampunk first-person shooter.  This includes the revolver itself, a 12-round empty magazine (removable, so the operator can swap out another pre-loaded magazine), one .44-caliber cartridge (modeled to scale), and one flare (which fits snugly into the lower barrel).  It is intended that the rear trigger should fire both main barrels, and the front trigger should trigger the auxiliary (flare) barrel, but that's really the decision of whichever developers want to use it.  All materials are procedural.
