Construc
Elma

Construc was a construction system that used steel strips (with no holes) held together by special clips. It was made in France in (probably) the late 1940s.

Elma appears to be the same as Construc, although it is not certain whether the jig was included or not. It was made in Germany in (probably) the early 1950s.

Strips, some formed, held with Clips. Most parts look like CONSTRUC but not sure if Jig is in ELMA.
