Mini VIN Plates

[Jarry]

So I found this mini in my dads garage while clearing it out the other week, I was looking at the VIN plate and have a few questions.
What does the very top number stand for?
Could anyone decipher the VIN itself?
Also I noticed that the Trim and Paint Boxes are not stamped, anyone know a reason for this?

I have attached a photo of said VIN plate however if it is unclear the numbers are:
031001
XK2S1N00717687

Cheers
Jack
