A Modern Toys / Masudaya 1950 radiocontrolled car, one of the first, with spark emitted radio control box.... I guess this must be the ultimate and most complex toy for its time.... The car and controller is in mint condition and fully functional! l would say you wont find anything like it! Check pictures! I have also added two films on youtube, showing its complex inside, and the second film while running.... The hissing sound is from the controller spark emitted signal. The sparks at the controller is also visible thru the blue glass. When driving to the left, the left blinker turns on, and when right turn the righ rear blinker blinks... Its all visible in the 2 films added below.... Only flaw is that the original box have its dents and scratches, but it has done its job well, which is to protect the car.... If you check up this car at the internet, you will see its pricing.... As always l really hopes it will end up at a serious and competent collector, this is really a mechanical masterpiece! Now check the short videos! Inside working: https://www.youtube.com/watch?v=NQmHQjf8-Pc Driving: https://www.youtube.com/shorts/qLMkCKnQgp0
