Educational model of a Wankel rotary engine, Europe, 1960s/70s

Description

An original vintage demonstration model illustrating the operating principle of a rotary engine, specifically a Wankel engine.
The model is made of metal and plastic and mounted on a stable base. It is equipped with a hand crank that activates the mechanism, allowing users to observe the rotor in motion and the engine’s operating cycle.
The distinctive colour scheme (blue and red – intake and exhaust channels) and cross-section make it an excellent object for: –
educational purposes
– collecting
– decorative purposes (industrial/loft/office interiors)
Models of this type were used in technical schools and universities in the 1960s and 1970s, particularly during the period when rotary engines were gaining popularity.

Interesting fact (relevant to the sale)
The Wankel engine was developed in part by Mazda, making this model particularly appealing to motoring enthusiasts as well.

Good vintage condition:
mechanism in working order – rotates manually
visible signs of use and patina (consistent with its age)
scratches in the paint on the base
no major structural damage
