  We show that the effective field equations for a recently formulated
polynomial affine model of gravity, in the sector of a torsion-free connection,
accept general Einstein manifolds---with or without cosmological constant---as
solutions. Moreover, the effective field equations are partially those obtained
from a gravitational Yang-Mills theory known as the Stephenson-Kilmister-Yang
(SKY) theory. Additionally, we find a generalisation of a minimally coupled
massless scalar field in general relativity within a "minimally" coupled scalar
field in this affine model. Finally, we present the road map to finding general
solutions to the effective field equations with either isotropic or cosmologic
(i.e., homogeneous and isotropic) symmetry.
