I dunno, comparing the stock rim to the Oregon one, the Oregon one was not finished as well, and it had the hairline crack in it. I will have to get some more rims down at the Stihl shop in Cottage Grove where I get my RM loops made. They seem to have an old cashe of rims and chain there.
The ones I have studied under a magnifying glass, look exactly, repeat exactly the same, except for the logo.
