EDIT - SOLD
These are very well made vintage wheels. Similar in style to Centerline, but made by Chassis Engineering/Monocoque in the 70s/80s. Lighter than the same sized Fuchs wheel, and easily repairable if damaged (apparently). They use aerospace bolts in the outer edge, and there is a 3 ply center - I believe (though I don't know) the center ply is magnesium, due to it's darkere color and being non-ferrous. These would make a wide body/RSR car.
