Lot # 66 - Vintage Kenner Hydro-Dynamic & Bridge Sets with Motorizing Kit

  • Kenner Bridge and Turnpike Building Set: Focused on civil engineering, this set features girders, trusses, and roadway sections for building elaborate highway systems, interchanges, and suspension bridges.

  • Kenner Motorizing Kit: A rare add-on designed to bring these static models to life. It includes a battery-operated motor unit, pulleys, and drive belts to power elevators, drawbridges, and rotating structures.

  • Supplementary Building Set/Parts: An additional set (or large collection of parts) to expand your builds, providing extra girders, panels, and connectors for massive "skyscraper" scale projects.

  • Features & Design:

    • Era: Circa 1960s, capturing the industrial and futuristic aesthetic of the time.

    • System: The classic "Girder & Panel" construction method, where vertical columns are set into a Masonite baseboard and horizontal beams lock in to create skeletal structures.

    • Material: Durable molded plastic in vibrant 1960s colors (yellow, orange, blue, and green).

      Condition Note:

      These sets are in vintage, played-with condition. While they appear to contain a vast number of parts, they have not been inventoried for completeness and are sold as-is. The boxes show authentic age-related shelf wear.
