It looks like there was an obverse mark before it was worn. If so, by extension it can't be a bust 2 -/Arrow. Joe's article on this issue also states that all bust 2 coins seen are from the same obverse die. This is a different die and so, despite the lack of detail, all the indication are that it is highly unlikely given it is very rare. It isn't impossible that a bust 2 could appear on a different die, but I wouldn't bet on it.
