  The results of [1,2] on linear homogeneous two-weight codes over finite
Frobenius rings are exended in two ways: It is shown that certain
non-projective two-weight codes give rise to strongly regular graphs in the way
described in [1,2]. Secondly, these codes are used to define a dual two-weight
code and strongly regular graph similar to the classical case of projective
linear two-weight codes over finite fields [3].
