Let $J^rT^*M$ be the $r$-jet prolongation of the cotangent bundle of an $n$-dimensional manifold $M$ and let $(J^rT^*M)^*$ be the dual vector bundle. For natural numbers $r$ and $n$, a complete classification of all linear natural operators lifting $1$-forms from $M$ to $1$-forms on $(J^rT^*M)^*$ is given.
