N2 - We attempt an extraction of the pretzelosity distribution (h1T) from preliminary COMPASS, HERMES, and JLAB experimental data on sin(3φh-φS) asymmetry on proton, and effective deuteron and neutron targets. The resulting distributions, albeit with big errors, for the first time show tendency for up-quark pretzelosity to be positive and down-quark pretzelosity to be negative. A model relation of pretzelosity distribution and orbital angular momentum of quarks is used to estimate contributions of up and down quarks.
