Just because I'm an old coot and remember when everybody had to have mag wheels or they weren't cool, I would add that there were two companies who made the "real thing" from magnesium. Halibrand and American Racing.
Halibrand still does and I don't know about American Racing.
The wheel you have isn't a bad looking mag at all and aluminum is a lot easier to take care of than magnesium.
Go to
www.halibrand.com to see the father of mag wheels.
This also applies to those who want original wheels for their Cobras. Halibrand still makes them to order.
While taking nothing away from Lynn Parks and his Trigos, there are differences that are very obvious if you know what to look for.
