John:
I'm virtually certain that it's the same gun. The serial number of RTBA's R9 had five characters which could be clearly seen. It sold for $1,736.00. The serial number of the one now up for auction shows four characters, but they are the same as the first four on RTBA's pistol and the item description states, (*Last digit(s) digitally obscured in photos for security reasons). The starting bid this time is $1,795.00.
Afterthought: I'm a capitalist through and through, but I rather regret seeing one of these R9 masterpieces being bought and flipped like some used car.
