Have I received OEM or aftermarket parts?

Just bought two new OEM wheel hubs (http://www.rimmerbros.co.uk/Item--i-TAY100060P1) from Rimmer Bros and I'm a little suspicious that they aren't OEM.

I've had a good look at them tonight and I've noticed they don't have Wabco branded on the sensors which is clearly visible on photos of other sellers OEM hubs.

I've also noticed that Rimmer Bros use the same photo on their website for both aftermarket and OEM hubs.

Has anybody any experience that they would care to share?

Phone them and check - they have always been pretty straight up with me.

Does it have Timkin stamped on the bearing

I've sent them an email and will give them a call in the morning.

No it doesn't have Timkin stamped on the bearing. I'm guessing that's a bad sign?

The original hubs I took off my D2 had Timkin bearings

I bought an OEM filter kit from them and ended up with Britpart stuff. I still used it, but got them to refund the difference between the OEM and Aftermarket filter kit prices.

Thanks for your comments everyone. I'm still not entirely convinced they are OEM, but I need to change the hubs ASAP so will use them and report back if/when I have problems. I do approx. 25-30k miles per year so issues will show up pretty quick.
As a point of interest, this is the response I got back from Rimmer Bros when I queried if I had been sent OEM or after market parts:-

"The hubs sent we code to more than one supplier, and if our primary supplier were unable to fulfil their order our purchase dept would locate the hubs from our second source, which in this case would still be OEM as described, I trust you may understand that with some 40,000 different parts on the shelf we would need a team of photographers picturing and updating our web site six days per week in order to reflect the specific part on the shelf against that specific part number.

Our web site does offer the advice that the illustrations are for guidance, and may not be the specific illustration of the actual part on the shelf. "

That's a bit of a non-answer!
