Well since this thread has been bumped... I took a gander at the British page of the spreadsheet and I have to say my hat is off to you, Legiondude - you obviously put a LOT of work into it!!
One tiny thing: The Mk VIC is listed as "limited production" but this one website says 334 vehicles were produced, which is more than the entire production run of the Tetrarch or Challenger (listed in the wikipedia article).
