As new, I'm not sure it has ever been fired.
The Remington Model 1858 (Pietta) was one of the most powerful and rugged single-action revolvers of its day. Easily removable, replaceable cylinders made reloading extremely fast. The highly realistic Model 1858 New Army .44-Caliber Black Powder Revolver delivers that same power with its blued steel construction, polished brass trigger guard, octagonal barrel,walnut grips and color case hammer. Center fire cylinders for it are available on the internet.
