You must have bought the one on ebay .

I like this version of the Thrust Bearing with the oil grooves .
It was an improvement over the original design that had no grooves .
Looks like it needs a little clean up . Do it gently !
No sandpaper or rough stuff .
The cam gear will be easy .
Keep up the excellent hunting .
