Crazyb's wheels are also cross 3.
His is a later 70's version. Mine are 1971 (original wood filled Weinmann tubulars), 1973 and 1974 (with original Weinmann clinchers).
Given my choice, I would prefer 3 cross. I recall reading somewhere that was actually stronger anyway.
You have some VERY sweet looking Paramounts! Time to take them out and enjoy them!
