Austrian 12-inch siege howitzer (GW). WW I
Austrian 30,5-cm (12 inch) Mortar in the Dolomites, Monte Calio.
Nice big guns. They seem kind of short, though. Must be intended for targets in close proximity.
Isn’t the word ‘howitzer’ a really good word? I like it a lot. And so did ‘Howitzer Al’ Houlihan.
