I have a set of 5 Fuchs -- i believe all are date stamped 11/70. That means no 'hearts.' Centers have been sprayed black, but no prior chrome or over-polishing. Plenty of rash on the original anodized lips.
Looking to trade for a set of flat 15 X 6" Fuchs in similar condition. I expect the early ones are worth about $150/wheel more than the later ones [given equivalent condition], but let's discuss.
