Dunno why,but the first one they made was pink....hence the name Flamingo.Granted they could have random numbers but then you wouldn't likely get 2 random numbers in sequence.
Cant see them having 500 ready to go but nice for psychological effect, could well include lots of prototypes if it is a sequential list as well. and could plenty are in production and on the production line, shells for the rockets without the working parts etc as the ones with 479/480 are far from complete. You can see 6 in production in one of the pics which seems to be a tiny section of the factory.
