R 811340 Set Squares 30-60deg 40cm

Made of crystal-clear acrylic.
With divisions and bevelled edge.

This huge and beautiful triangle square really impresses by the size and quality.
Pairs with R 810 340 45deg square.

From What I have found out it was available at the end of 1970s, before that only orange and smaller models were offered.
hard to imagine there was a larger size (50cm) as well.

In catalogs is shown with additional marks, which this one doesn't have.
