Mine:
EAU0002XX - 4 Jan 2008 - 9mm Compact
EAU0080XX - 30 Jun 2008 - 9mm Compact - Desert Sand Digital. Controls, & ejector appear to be phosphate, barrel has a harder finish because only very faint smileys like my P220 Combat.
EAK0007XX - 30 Jun 2009 - 9mm Compact TB, Green Digital. The EAK0007XX frame is currently mated with 45 Compact Upper & Grip.
I sold the upper with a black grip, frame # EAU0164XX ( which began as a 45 Compact Red Box - Date Unknown) & the barrel from EAU0002XX.
EAU0192XX - 5 Aug 2009 - 45 Full Size, Red Box with SN labeled over so Date may not be accurate, which appears to be the case since it is out of sequence.
