This is a simple compound monocular with push-tube focus, inclination joint, square stage, sub-stage mirror, and square base. It comes in a green wooden chest which also holds slides, apparatus for simple chemical experiments, and a “Microscope Manual of Instructions.”
This was made and marketed by A.C. Gilbert, a toy company that was established in Westville, Ct., in 1909, and that introduced the Erector Set a few years later. Gilbert began offering microscopes for children in 1932.
