1970 The Demon Prices Page

Casting #: 6401
The Demon
Designer: Darryl Starbird / Larry Wood
Production Run: 1970-1971
Note: Produced only in Hong Kong. All models should have a black painted roof. Black was the common interior color, but there was a white interior variation that was much harder to find. This does add a premium.
