Seeing the Stingray Submarine Aircraft Carrier again reminded me of a hunch I had a while back. Are the rear fins of the rare Century 21 Submarine Aircraft Carrier toy the same as those on the even rarer Fairylite Fireball XL5 toy? I've blogged it before but it needed better pictures, which you see above. I guess these prove one and for all they're not the same toy part. BTW do rear fins like this have a technical NASA-esque name?
