Abstract:	We present constraints on the formation of the sdBV+dM eclipsing binary PG 1336−018 derived from a detailed evolutionary study. These are confronted with the orbital solutions permitted by our high-resolution time series VLT/UVES spectra and high-speed multicolour VLT/ULTRACAM photometric observations. We found two orbital solutions (MsdB = 0.466 M⊙ and 0.389 M⊙) which are consistent with the sdB primary having gone through a core-He flash and a common-envelope phase described by the α-formalism.
