Jouef reference 701. Already existed in 1956.
Can be fully dismantled thanks to a clever system of angled slide profiles. There is a built-in lighting system using a 4.5 V flat battery. The lighting is done by moving a bench on the platform.
The walls being translucent, I painted them inside aluminium colour. I had covered the platform with gravel made of coloured cork matching that of the platforms in extension. They went to the waste disposal, with the layout to which they were too well fixed, and which had to be cut to get out of the attic…
The orange colour of some walls is not due to a painting, but simply to the patina of time. Curiously, the colour of the main façade has not changed.
