Wow, thanks for that picture,
@peramangkelder
That is quite different from the ones I remember, from the 1950's.
Though there are some definite similarities, as well. The compartments in the box, and some of those shapes.
Though as I stare at that, I begin to remember and recognize more of it. Yes, it did have painted colors on a few of the metal pieces, though mostly had worn dull, by the time I myself played with it.
It was a long-lasting indestructible toy that lasted for numerous children!
And yes, I remember those "cables" ...string, with the small hook.
Though I do not remember the larger circular pieces shown there.
OH, those are wheels! Yes, metal wheels, and different sizes.
It's funny how it is coming back to my memory, in small pieces and memory spurts.
Thanks for sharing about that!
The sets also might have differed on different continents.
