Can't figure out what this means. Its a 404 chain, 52 on the drive link. But what is the AN on the cutter? Oregon's site says A is standard but there is no N listed that I can see? Any body know?
I just attended a class from Oregon. 52 is an older chain. I have a new loop of 52 for a 6' bar and he said to save it for a collector. I think that it is 404 square.
