label: Description
content: In its complete form, the model has four congruent parts which are arranged with tetrahedral symmetry. This example has only three of those parts and they are presently disjoint. The three pieces present each have the dimensions given. Identical curves are drawn on them. A paper tag reads: Fl. 4. Ord. mit 4 Doppelebenen. [/] Verl. v. L. Brill. 9. Ser. Nr. 6.
