Using stellar evolution models of two different kinds, one with convective cores determined by the Schwarzschild criterion, one with enlarged convective cores, we discuss the masses of the WR stars in a number of double-lined WR binaries. For the main group of systems the mass of the WR-star is between 10 and 20 M.
