We revisit Wyman's ``other'' scalar field solution of the Einstein equations and its Sultana generalization to positive cosmological constant, which has a finite 3-space corresponds special case stiff fluid proposed by Buchdahl Land and, later, Iba\~nez Sanz model relativistic stars. However, there is hidden constant peculiar geometry prevents use this spacetime
