Tinkertoy Classic Wooden Sets
These are the building toys of my memories with just a few tweaks. (Was "Tinkertoy" stamped on the round pieces? Aren't they just a tad bigger than I remember?) All pieces are real wood and fit together in the classic way straight pieces into round hubs. Some pieces allow for movement. An included brochure shows detailed instructions for constructing nine (Basic set) or fifteen (Deluxe) models.
