Boettger: German Rider engines

While in the US 10 inch Rider engines seemed to be enough, German licensees offered engines up to huge 12 inch machines. Their Modell H 2hp engine by Böttger in Dresden/Saxony stood 99 inches high with a floor space of 75 x 43 inches, delivering 4500 USgall/h @ 50 feet. Their competitors Monski of Eilenburg, also in Saxony offered a similar engine, more about that certainly by Gerd Maier in due course.
