Mazda Rotary Engine Display Model Functional, Vintage Dealership Promo Item
This is a working display model believed to have been distributed by Mazda to dealerships as a promotional tool when marketing their rotary engine vehicles.
Based on the rotary logo design on the back, it is likely from around May 1967 to the early 1970s, coinciding with the launch of Mazda’s first rotary engine car.

Condition & Restoration Details
When acquired, this unit was non-functional and heavily soiled, both internally and externally.
Full disassembly, cleaning, and mechanical restoration have been performed:
The seized internal drive mechanism was cleaned, re-greased, and now rotates smoothly.
Lighting is also fully functional.
Transparent parts, likely acrylic, have been cleaned to remove mold and other grime.
Some deteriorated colored films that transmitted light from the fluorescent lamp have been replaced using professional-grade lighting color filters.
Attached with 3mm-wide acrylic double-sided tape.
The light-diffusing sheet around the rotor was deformed and peeling; it has been replaced with a low-adhesion residential window film, closely replicating the original.
No repainting has been done, in order to preserve the original appearance.
The fluorescent ballast is labeled “60Hz”, so the motor is likely also 60Hz-specific.
Operation
Plug into a standard 100V outlet and the model powers on:
both the circular fluorescent lamp and the rotor operate simultaneously.
The motor and lighting are wired in parallel and cannot be controlled separately.
