Abstract
We have obtained velocities for the binary Cepheid V350 Sgr at the Dav id Dunlap Observatory. An orbit has been derived combining these data with velocities from the literature. The spectral type of B9.0 V has b een confirmed from an IUE spectrum, leading to a mass of the companion of 2.5 M.. The uncertainty in the mass is also discussed.
