The K0 SK±π∓ final state in two-photon collisions is studied with the L3 detector at LEP at e+e- centre-of-mass energies from 183 to 209 GeV with an integrated luminosity of 664.6 pb-1. The η(1475) and f 1(1420) mesons are observed and their contribution is separated by measuring the formation rates as a function of the photon virtuality Q 2. The η(1475) is found to be dominant for Q2 0.01GeV2 and its two-photon width is measured to be 0.23±0.05 (stat.) ±0.05 (sys.) keV. At higher Q2, the f 1(1420) is formed and decays to K*(892)K. The γγ coupling and form factor parameters of this state are measured to be Γγγ ≤ 3.2±0.6 (stat.) ±0.7 (sys.) keV and Λ1 ≤ 926±72 (stat.) ±32 (sys.) MeV, respectively.
