Forging a gun barrel

This is my first attempt at forging a gun barrel as a colonial gunsmith would have. It's forged from a section of a wrought iron tire off a wooden wagon wheel. This effort is only the first couple steps for forging a barrel. Additional steps include forging (and filing) the barrel to an octagon shape, drilling the center hole larger, then reaming it to a final bore size, putting in the spirals, adding a breech plug and forging and adding the sights and hardware to mount the barrel in the stock. I may follow up with additional work on this barrel, but it won't be anytime soon. My goal for this effort was to see if I could do the forge welding.
