Vintage Nikko HAN-D-BOT, RC Robot, 1985, Partially Working, (H1)

As per the title this is partially working, when batteries are inserted it goes forward and back but the arms do not operate therefore I am selling this for spares or repairs, could be a good repair project for a vintage toy collector.

In good condition given the age but the box does show signs of wear.

Please see the pictures and take the above into consideration before buying.
