This plastic model represents the union of three congruent figures that each have two triangles, a parallelogram, and two irregular quadrilaterals as sides. These are arranged symmetrically such that several sides are coplanar. A mark on the model reads: 644b. A hexahedron (with museum number MA.304723.398) fits in an indentation in the top of the model. Wheeler also gives this model number M52. Wheeler writes of the combined model 694: “one-sided Hexahedron Reinhardt.
