Not sure. The book L'Artiglieria Italiana Nella Grande Guerra mentions this gun, so they must have been in service during WW1 and they were therfore not trophy guns they gained from the A-H empire after the war. Having said that, the book L'Artiglieria Austro-Ungarica Nella Grande Guerra shows a gun that appears to be the same gun, the Obice da 42cm M14. It appears that both sides used the same gun during WW1.

If it's true, then it becomes clear why the installations of these guns differ from each other.
