ID WW1 Italian Incendiary bomb

Another mysterious Italian incendiary bomb, or rather bombs as we are speaking in fact of 2 sizes (short and long versions)

After the 130mm incendiary that popped up in the thread on the unknown type French square bomb of 1915 (but may be it's logical if this 130mm incendiary was in fact of French origin, though widely used by the Italians).

Seems that these bombs are probably development of the 1915 "poiettili incendiari occasionali" made with a commercial petrol can of 18l, that was used to fill the tanks of the Italian airships.
This is a drawing and picture of this original device:


Could someone throw more light upon these development specific to WW1 Italian Naval Aviation
