Tinplate 1960 clockwork cars and roadway set with key

Unboxed. In fair condition but has some rust. Two of the cars are working but the green one isn't. It was mine as a child in the 1960's. When a car runs over and pushes down the metal bar it raises a piece of metal on the corner causing the car behind it to change direction and go under the bridge. It is as seen in the photos. Please look at the photos carefully- I've tried to highlight any flaws. From a smoke free home. Bids from the UK only please.
