Identify Bathroom Faucet

[northstar]

I need to replace this cartridge but don't know the part/brand. I went to Home Depot, couldn't find a match, an employee there was sure OSH had it. I went there, they were even more clueless. I'm hoping I'll have better luck here. Any clues would be greatly appreciated.

That stem can fit many brand faucets. Look at the base of the spout front & back real closely for a name brand or take the stem to a real plumbing supply store and they should be able to match it with no problems. It might be Kohler

looked in my stem book, this is the only one that has the small groove splitting the broach and does show the clip but has the groove for it.
