FS: Powertap 2.4+ Hub - SOLD

I am changing to a Quarq and just had this hub removed from one set of my wheels.

I bought this new and had it installed in 2010 (Although I believe it is a 2009 model because I updated it to ANT+ to work with my Garmin Edge 500). It looks like new (9.5/10) as it was only used for approx. 100 miles (I had two other powertap wheels that I used)

24 Hole, Shimano compatible, upgraded to ANT+. Looking for $675 shipped CONSUS (I think I paid close to $1300 for it).

Does this have the newer 15mm axle or the older 12mm axle?
