Single slot campy rims

Very early cars.

Those rims are valuable.

FWIW, 7" single-slot Campys are fairly common in the U.S. 8" single-slots are harder to find, and I've only seen photos of one set of 10" single-slots (on an OZ Pantera), and those may have been massaged with a TIG welder and milling machine. Single slot magnesium wheels still need annealing every 10 yrs or so.

There were also triple-slot wheels that apparently are even rarer in the U.S.
