The Laird Rams didn't go to the Condfederacy thanks in part to the sharp eye the US Embassy kept on British shipyards not the least of which were the Laird shipyards. The Japanese Navy bought the Laird Rams and used them for a number of years there is a Wiki article on them most likely others as well.
There is a technique in which countries buy arms even if there boycotted or under sanction called " third party transfer" and it was used at least several times by the Confedracy . The warship known as the "Stonewall Jackson" started life in a French shipyard and due to US diplomatic pressure it couldn't be sold to the Confederacy so it was sold to the Dutch who then somehow sold it to the Confederacy but by the time it got close to US waters the war ended so the captain went to Havana and then the US Counsel General purchased the ship from Spain.
The Alabama ,Florida and Shenendoah were technically not war ships but cargo ships and they were equipped with cannon if I remember right if the Azores far from the UK.

Hi lefty, thanks for sending me to Wiki, what would we do without her? https://en.wikipedia.org/wiki/Scorpion-class_ironclad
I still can't find any reference to the Japanese Navy, perhaps there was another ship you're thinking of?
The Laird rams, HMS Scorpion (ex-North Carolina) and HMS Wivern (ex-Mississippi), both joined British Channel Fleet in 1865.
Scorpion went to Bermuda in 1869 as a guard ship and a plan to convert her to a harbour defence monitor with all-around fire was dropped 1878. She was fitted with searchlights and quick-firing guns in 1890 and was sunk as a target in 1901, raised in 1902, sold in 1903 but sank under tow to Boston.
Wivern burst one of her 9-inch guns in 1867, but none of the 13 people in the turret was injured. The ship became a guard ship at Hull early in 1870 and was then placed in reserve from 1870 until 1880. That year she was sent to Hong Kong where she became a harbour defence ship. She became a distilling ship in 1898 and was sold in 1922 for scrap.
