We report on a new precision measurement of the longitudinal polarization of positrons emitted by polarized 107In nuclei. If interpreted in the framework of the manifest left-right symmetric model, preliminary results yield a lower limit of 303 GeV/c2 for the mass of a possible, predominantly right-handed W gauge boson.
