Nully pointed this out to me and I tried to bid last minute but didn't win, unfortunately. I was curious as to see what the board for this unit looked like. The name suggests that it was before the DUO-R but sequential to the naming convention to that of the TurboDuo which I found quite interesting. If it was a fake, it's a very good one. It would have meant that whatever company manufactured it is familiar with these numbers already and mimicked them to look legitimate. However, I do not think this is the case. I am going to take a guess that there were at least 200 of these units made, likely sent to retailers/testers or what have you, to showcase the new, sleek unit prior to its inception and when the final product was made, it was renamed to the DUO-R... or at least, it's my speculation.
