The Algol system RS Sgr was reobserved at the Cerro Tololo Inter-American Observatory in 1983 and 1984, with a dispersion of about 9 Å mm-1 in the second-order blue of the grating of the 1.5-m coudé. The new material has disclosed the presence of the secondary component in the Ca II K and H lines, although the latter cannot be measured because they blend with the H lines from the primary component. By adopting Baglow's value for the orbital inclination, a mass is derived of nearly 7 M_sun; for the primary and about 2.5 M_sun; for the secondary. Hα displays variable incipient emission, thus suggesting that we are perhaps dealing with an interacting system caught before any drastic mass-loss transfer had taken place.
