At first glance, it looks ok. The dark rings are where the ring travel ends. I want to say I see crosshatching in the cylinders but it's not clear. I'm no expert. Check all the bearings as well just to see all condition.

Also, if you can't catch a fingernail on any of the discolored spots, than there's likely nothing to worry about.
