Model of an F-1 engine, full-scale. Approximately 19 feet tall x 12 feet diameter. The upper portion of the engine made of steel and showing relevant parts such as turbopump, heat exchanger, turbopump exhaust manifold, fuel inlets and gimbal block. The thrust chamber and nozzle extension of fiberglass with tin or aluminum covering representing the thermal protection system (also known as "foil batt"), this applied subsequent to the World's Fair. Some weathering.

The F-1 is still the most powerful single-chamber liquid-fueled rocket engine ever put into service. Manufactured by Rocketdyne, five F-1 engines were used in the first stage of each Saturn V rocket, each generating 1.5 million pounds-force of thrust—more than all three Space Shuttle main engines combined.
The present model comes from the 1964-5 New York World's Fair, held in Flushing Meadows, Queens. At the fair was a Space Park which featured scale models of Gemini-Titan and Mercury-Atlas rockets, the Mercury spacecraft Freedom 7, an Apollo CSM and LM, and the SI-C first stage of the Saturn V, complete with its five F-1 engines. In the decades following the Fair, most of the models remained in place. In the early 2000s, the New York Hall of Science expanded into the Park, tidying up, and restoring the models. The Saturn V first stage was dismantled, and its model F-1 engines were distributed between several museums.
