The formation of the eccentric, long period binary WR 140 (HD 193793, WC7 + 04-5V, e= 0.8, P = 7.9 yr), in terms of an eccentricity modulated late case B of mass transfer, is investigated. Using only stellar wind models, it is impossible to obtain a combination of a spectral type O4-5 together with a WC star.
