OEM Rotors - check for authenticity?

Hey guys

For the OEM rotors on the W204, are there any MB logos indicating its authenticity?

I bought a pair but nowhere does it say MB or have a logo. Is that normal?

Thx

unfortunately this why a lot of people buy thinking its authentic, and when you recieve them from eBay buyer theirs no way confirming its authenticity.
very frustrating.

Bought from a wholesaler. Everything they sell is genuine, and everything has come in a box previously. The rotors didn't, and while i'm not accusing anyone of anything, I was just surprised there was no OEM marking on it, that's all.

It seems like everyone here has confirmed there is no OEM marking anyways on genuine stuff so......

There has to be somewhere! I do know, if there are markings they will be on the side of the hat. Min/max specs and maybe a part number. Call the dealer and ask the parts department to get some real answers.

It looks to me that the rotor you posted a picture of, appears to have a zinc plating on it or am I imagining that?

I am wondering if OEM is not supposed to be plated.

HOLY CRAP. Thank you!!

Yes, I see a MB logo and then the part #. It's SOOOOO faint that unless you know something is there it's impossible to spot. Thanks!!
