OZ wheels to identify. Please help!

[alpex297]

I have a nice sets of OZ wheels, that I got altogether with my most recent car that I bought on eBAY, and I was not able to identify the
model of these OZ wheels yet . They make my car
"fly" very nicely. I wonder if you can help me
find out what is the name of these wheels, they are
not in the current OZ catalog, obviously they come
from a more distant year in the past.Since I cannot post files attachments here you may want to give me your email address so I could send you the picture if you are really good at OZ wheels!

On the other hand, some of the silver plating had been
suffering some corrosion, abbrasions and I wonder if
you can suggest how can I take care of them, can they
be replated selectively ( ) on the affected areas? and
where? I live in New Jersey.
Thanks.
