HD650's driver. Different serial numbers?

[murphythecat]

I recently broke one of my hd650 drivers. so I now have one driver that is from 2007 and the other from 2015.

the 2007 driver has written on it: 049785
the 2015 driver has written on it: 600129

I have two pairs of hd650, and my new pair of hd650 also has the drivers with 600129 serial number...

is the 2007 driver a genuine hd650 driver?

Pretty sure the HD650 has had some driver revisions over the years.  Hopefully someone else can pop in with more info.
