Early Marklin toy hot air engines

These three toys were all made before 1914. The water pump is an improved version with cooling fins and a more efficient beta type engine. The fan is geared just like its larger Jost fan counterparts and the twin has two power pistons and a single displacer. I have never found the model numbers for the fan or water pump. Anyone?
