Until I see a better photo (without the drive side taper partially hidden) I won't say this spindle (actually axle as it is the rotating element) has off set tapers. The drive side "cup" flange hides the base of that side's taper from view.
As I mentioned in my first post there's some manufacturing tolerance WRT the ends of the taper. As always the best way to find the best BB axle length/fit is after test installing. Andy
