TX 204
Another great aircraft from the TV series ‘THUNDERBIRDS’. This heavy duty cargo plane was featured in the first episode - ‘Trapped in the Sky’ - and ‘The Mighty Atom’. .
I don;t know what SAF stands for. More than likely this is just the back half of a USAF decal that the model makers used because it looked good appropriate.
In 1/72nd this would be maybe 1 foot (30cm) long. Probably this would have come in a grey plastic.
