Idéal Mécanique

Idéal Mécanique was a construction system using mainly aluminium parts. It was made in France probably shortly after WW2.

There are two variations on this system (otherwise parts are virtually identical):
Idéal Mécanique[1] - copper anodised parts with 3.8mm threaded parts
Idéal Mécanique[2] - red anodised parts with 4mm threaded parts.
