Mint factory sealed American Flyer S gauge 20421 accessory pack. The contents inside are a 25515 rocket sled and 25046 rocket launcher flat car. Both come with control buttons and other odds and ends. The box is perfectly sealed and high grade as seen in the photos with presumably C10 contents. I have added a photo taken from the internet of what was photographed regarding the components of the package. The box is still sealed and the phot is only a representation of what is inside.
