This plastic model is the mirror image of model MA.304723.397. It represents the union of three congruent figures that each have two triangles, a parallelogram, and two other unequal quadrilaterals as sides. These are arranged symmetrically such that several sides are coplanar. A mark on the model reads: 644b’. Wheeler also numbered it M53 among his one-sided polyhedra. See also MA.304723.397 and MA.304723.398.
