Chad Valley Bridge and Panel Construction Sets
Chad Valley had a range of Bridge & Roadways and Girder & Panel Construction Sets. These were used to make models of bridges and Girder Framed Buildings using plastic components. They were sold in the UK under licence from the USA company, Kenner. They were sold from the late 1950s. Not sure when production stopped.
