Wheeler, Albert Harry

Description

This hinged model has three pieces (the blue and yelow plastic are attached to the same triangular base, while the red and white piedes are attached). It is not hinged. It can be arranged as one large square or two adjacent squares of different size.

The case is marked in pencil on the bottom: De Morgan.

Compare MA.304723.769 (a hinged version of the model with only three pieces) and and MA.304723.775 (this is not hinged).
