Thanks to Dan Morgan for contacting Apogee directly on this one. Here's the answer:
There are two versions of the Mini-Me and in fact there are not that many of the first revision units out there. I believe there was only around 90 of the first revision Mini-Me's.
There are a few of the newer revision units out there that are in black cases and then we switched to the all silver cases after a short run.
The S/N you gave is indeed the newer revision model of the Mini-Me.
The differences between the two revisions is the ability to run a battery as low as 6 Volts and the ability to change the gain structure of the Mic level from low to high gain via jumpers on the main board.
I hope that helps.
