Here are lots of paper Paddlers, created by quatzalcoatl. The series includes Dresden, Leipzig, Pillnitz, Meißen, Stadt Wehlen, Kurort Rathen, Pirna, Diesbar, Kaiser Wilhelm, Wappen von Minden and Krippen. The above example photo is a finished PS Diesbar.
PS Diesbar was built in 1884. Today it is the last steamer of the Dresden fleet still fired by coal. It is globally unique, in that it is propelled by the world´s oldest operating marine steam engine, an oscillating marvel built by John Penn & Sons in Greenwich, England in 1841. The engine of the “Diesbar” was designated a “Historic Mechanical Engineering Landmark” by the American Society of Mechanical Engineers (ASME) in 2008. [Source:Saechsische Dampfschiffahrt]
