It is a piece of Rotary Engines history. A First Generation, beautiful Dealership Sales Sample, which was made by the NSU factory for their dealers to explain the unusual function of the "new" Wankel motor. It has a long development history with ups and downs until it was used in 1960 in a NSU Prince vehicle, not quite successful. A few years later 1963, the refined engine was put into series in a NSU Wankel Spider car. This is the year of this great Dealer showroom model.
In 1967 then the factory went into production with the very futuristic, luxurious NSU RO 80 car, but Mazda was ahead of the game.
The teaching model is manually activated by a hand-crank on the flywheel, turning it in arrow direction, showing the movement of that Internal Combustion motor. At the side view it shows Intake (in Red) and Exhaust (in Yellow). On the opposite side is the spark-plug located. The two grey wires are connected to a battery compartment underneath, which light up the spark at ignition point. The front section is covered by an acrylic plate.
This is a RARE, very hard to find, original, FIRST Generation Wankel Motor model.
Dimensions are: base 11" x 7", the model stands 10" tall.
