  The north-west corner transfer matrix of an inhomogeneous integrable vertex
model constructed from the vector representation of $U_q\bigl(sl(2/1)\bigr)$
and its dual is investigated. In the limit $q\to0$, the spectrum can be
obtained. Based on an analysis of the half-infinite tensor products related to
all CTM-eigenvalues $\geq -4$, it is argued that the eigenvectors of the corner
transfer matrix are in one-to-one correspondance with the weight states of the
$U_q\bigl((\hat{sl}(2/1)\bigr)_1-$module $V(\Lambda_2)$ at level one. This is
supported by a comparison of the comlete set of eigenvectors with a
nondegenerate triple of eigenvalues of the CTM-Hamiltonian and the generators
of the Cartan-subalgebra of $U_q\bigl(sl(2|1)\bigr)$ to the weight states of
$V(\Lambda_2)$ with multiplicity one.
