I was just browsing my local charity shop and I happened to spot an unopened Airfix Series 3 RAF Emergency set. Bought it for a pound and took it home. On closer inspection I've just noticed that the artwork on the box is incorrect, the front of the box says RAF Emergency Set and the photo reflects this, however the four sides of the lid have RAF Refuelling Set written and photos of the refuelling lorries. Ive checked what the box should be like by checking on the web, and its obviously incorrect. Is this unique? Has anyone got one like this anywhere?
