High-resolution spectroscopic analyses of HBV 475 are presented based on emission-line profiles of H-alpha, H-gamma, He I 4921-A, He I 5016-A, forbidden O III 4959-A, 5007-A, Fe II 5018-A, and Fe II 4924-A. Radial-velocity analyses show that only a part of the line components coincides well with previous measurements. Other remarkable components are found which are shifted to either the violet or red sides, depending on the indicated phase. Highly resolved emission-line profiles reveal that they are not compatible with the calculated profiles of proposed theoretical models. 21 refs.
