I can tell you that I was one of the very first batch one, part two orders. The second order was placed when there was about half remaining (it was maybe when it said qty was 50 or so remaining). However, I know that a lot of people got orders in the 700's and 800's, but I think that these were orders made after the initial batch postings (where they identified all the non-paying buyers). My guess is that batch one, part two order numbers probably don't exceed 200000450. (This is assuming their numbering was progressive, but I'd say it was because of the time frame and units sold before my first and second order).
