We cannot less than firmly agree with Richard that the Mississippian paddlewheel should be done by Playmobil!! (I asked Playmobil for a paddlewheel and an USS Monitor).
Well, but as the immoral bellicist I am, I surely will transform it in a confederate battleship, hehe, with some cannons aboard. Or at least, a Confederate troop transport.
Where there paddlewheels in times of the Civil war???
