I have robot that my stepmom swears was a prototype that never went into production at Marx toys. Her dad worked for them in the 1960’s at the Erie plant. She stated that Marx would send toys home with employees over summer break to play with and return when school started back up. Evaluate for whether kids played with them and wear and tear. She said they did this quite often and said the “Big Wheel” was tested also. They opted not to make robot though. I can’t anything on the internet about the robot.
