Identifying Bontrager hub and/or freehub (photos)

I have what I think is a 2010-2011 Bontrager Rhythm Pro Scandium 26" rear wheel. It rode well for a few months before the rear axle was sticking and the freehub wouldn't coast. I took the hub apart and changed the bearings which helped a little but seeing the state of the freehub splines I would prefer a replacement freehub. Also, and I couldn't find a diagram to prove this, but I think I am missing some sort of nylon washer or o-ring that should be between the base of the freehub and the top of the adjoining bearing to prevent the bearing from locking up.

TL;DR: Can anyone tell me if there is any replacement freehub available for this rim, or where to find out? My local Trek dealer was useless.

    I forgot to add that the hub itself is hourglass shaped and branded simply as Bontrager with no other discerning marks.

    Fairly confident it is a Novatec B type freehub... and yes, there should be a washer, metal, not plastic. The dents on the freehub are not concerning, I have seen a lot worse...
    To be honest, I am more worried about the spokes you have destroyed when the chain got jammed there at some point

    Thanks for the ID! And yes the spokes were chewed up by the previous owner, but this hub issue was a lot harder for me to figure out than re-lacing the wheel. :smile:
