Bral (Il Costruttore Meccanico/Bral) Construction Sets
Il Costruttore Meccanico was the name given by Bral to its construction system. Later it was called Il Costruttore Bral. It was made in Italy from the early 1920s to 2004. The system can be divided into two main phases. In the first the sets were numbered from 000 to 4. They were later renumbered to 1 to 9 with some additional sets added into the sequence.
