Centra T-31 Wheel on a W126?
 

I found a set of these wheels (just a quick glance, so they could be knock-offs) of this wheel ---> [IMG]http://assets.************************/assets/product/105863/105863_200_1.jpg[/IMG]



Now, they do need to be rechromed and the center caps are missing but the over all condition did look okay. What's a typical price these sell for used so I make sure I'm not getting bent here?
Ideas on how much it'd cost to get rechromed?
How can I tell they're real as opposed to fakes?

Advice and info is appreciated...

The only suggestion I can offer:
 

find the website for Ronal -- they might be able to give more informations, since they sold those wheels, once upon a time.

Thanks for the tip, I found their site. :D
