Ah, I had one as a kid. Wish I still had it. One of the best Christmas presents I ever got.
My brother got one of these for his birthday as a kid but it was the early 1970s. So I think they were making these for quite a few years.They must have also come in different colors. You can see the differences between the box and the toy above but even my brother's version was different with a darker red and black for the arms and legs.
