Context.[GKH94] 41 and IRAS 04191+1523B were previously identified to be proto-brown dwarf candidates in Taurus.[GKH94] 41 was classified to be a class I object. The dereddened spectral energy distribution of the source was later found to be suggestive of a class II object. IRAS 04191+1523B is a class I object that is the secondary component of a binary. Aims. We determine the evolutionary stage of [GKH94] 41 and estimate the final masses of the two proto-brown dwarf candidates. Methods. We used archive millimeter observations to produce continuum maps and collected data from the literature to construct the spectral energy distribution of the targets.
