I never intended to bid on it. I wanted to see if he was a seller making an honest mistake or trying to hoodwink someone into buying a blackscrew OD-1 with some other pedal's silver screw attached.
Then he avoided giving me the serial number by dismissing my question.
His reluctance to provide me with the info just confirms my suspicion that this is a deliberate attempt to pass the pedal off as something it is not.
