Abstract:	Velocity curves of the system HD 214419 are obtained for the N IV 4058 and He II 4686 emission lines from prismatic spectra taken in 1951 and 1952. The emission and absorption features experience several phase dependent changes that are described in detail. A common envelope model expalins well the He II 4686 light and velocity changes. The system parameters are best derived from N IV 4058.
