According to an email that I received from Peter G. around October / November 2003, there were only 15 total of the AA lug style green anodized units made, of which I was fortunate enough to have received 4 (of the 8 requested) for Xmas gifts.
Since they were subsequently laser engraved with the names of the family members who received them as gifts (and are fully appreciated and used by their recipients) it is rather unlikely that any of these units will ever see the marketplace again.
Along the lines of wishful thinking here...if anyone that has any of the other eleven "orphans" would like to see them rejoined with four siblings, please PM. Thanks.
