  We present recent results for galactic WNL stars, obtained with the new
Potsdam Wolf-Rayet (PoWR) hydrodynamic model atmospheres. Based on a
combination of stellar wind modeling and spectral analysis we identify the
galactic WNL subtypes as a group of extremely luminous stars close to the
Eddington limit. Their luminosities imply progenitor masses around 120 solar
masses or even above, making them the direct descendants of the most massive
stars in the galaxy. Because of the proximity to the Eddington limit our models
are very sensitive to the L/M ratio, thus allowing for a direct estimate of the
present masses of these objects.
