Meca
Constructivo

Meca appears to be a construction system with many of the parts similar to Meccano. The manual models are taken from a Meccano manual. It was made by Disa in Mexico in (probably) the mid to late 1950s.

Constructivo appears to be virtually identical to Meca. It was probably made in Spain although it could just possibly have come from Mexico. It is also likely to have also been made by Disa, in (probably) the mid to late 1950s.
