Not really, but this Prohibition-era whiskey-running submarine, preserved at the Grand Gulf battlefield, is still pretty cool. Other than the lack of a spar torpedo and of course considering that it was powered by an automobile engine (from a Model T) it is strikingly similar in appearance to the H. L. Hunley.
This isn’t really a submarine, tho, but is actually a semisubmersible like the present day “narcosubs”. Still, it would have been a great asset to besieged Vicksburg, where it was used later. As it was, the Confederates used swimmers to bring in small items like dispatches and musket caps, but their capacity was very limited.
