We present extensive high-resolution ´echelle and grating spectroscopy from Ondˇrejov, Calar Alto, Victoria and La Palma. We apply spectral disentangling to unveil the individual spectra of the two stars and obtain new spectroscopic elements. We perform a detailed abundance analysis by f tting non-LTE theoretical line prof les to the disentangled spectrum of the evolved primary star, and reveal an elemental abundance pattern reminiscent of a typical nearby B star.
