At the time in the seventies, Meccano France SA launched and produced their brand new famous dark blue MECCANO Construction Kits Set 1 to set 10 Boxes Model Range until the early 1990s, which was considered by many MECCANO collectors today as the nearest updated model range of the original British made Meccano. These were also sold in conjunction with the smaller "Complementary Sets CX Series" so that the builders could make more technical and more realistic working models with his own existing normal sets, making it more demanding and harder per kit for the builder or owner as the sequence MECCANO Set 1 TO Set 10 was available.
