What brand of mixture screw is this?

I took this off my new 2003 WR450 since the bike was running poorly and I thought the jets were dirty... Turns out I had an o-ring that went bad and was flaking apart and getting into every oriface it could! Problem is, the guy that sold me the bike said it's a JD Jetting screw, but I can't find one on their site that looks like this. I need to get the new o-ring and washer (still have the spring) but it would be nice to know if an OEM o-ring will fit all the same or where I need to go next to get this screw back where it belongs.

Anyone recognize it?

Don't recognize it, but an oem ORING is what you want for all fuel screws.
