This was in my photo archive and I've only just noticed it. Its from an Ebay auction earlier this year of a Century 21 Project SWORD Cape Kennedy Set.
The odd things is that the base of the rocket has what appears to be a panel missing from the side! Its a very neat rectangular hole and looks like it should be there!
I've never noticed this on my own toy and don't recall it when I was a kid. I shall have to go in the loft and check mine but in the meantime any ideas readers?
