This original document makes reference to the Italian priority date 1917-03-16. While this patent is not called outright an addition, within the British system, it does make overt reference to Patent GB-1915-14157. The earlier British patent does not make reference to an Italian parent but we have identified Patent IT-1915-150227 as a likely source.
