Hello,
I own a 070 universal building set from 1967 or so (photo1), but this one has cardboard inlays instead of the plastic ones you can commonly find (photo2). Does anyone has an idea whether it is an older type, or some transition box? I cannot find more info on this. Except: the set 050 from 1964 has similar inlays (photo3)...
Thanks for helping me out!
