grey plastic box, with ballbearings, and question & answer cards

[Van_Whistler]

My mother bought me a big grey plastic box game. (years ago)
It had question and answer cards, multiple choice answers.
The cards had holes in them, one hole for each answer. Three answers per card I think.
The cards are placed on top of the box, you put the ball bearing in the hole of the answer you think is correct.
If it is correct, the ball appears at the bottom of the grey box in the "you are correct" chamber.
If chosen a wrong answer, the ball appears in the "you are wrong" chamber at the bottom.

The game didn't come in a box, as she bought it at a second-hand sale, not seen anything like it before or since, and I would like to get my hands on one.

Remember one of the questions was "How many bones are in the human body?"
Surprised to learn there are over 300 bones!
