26 cm Minenwerfer M 17
The 26 cm Minenwerfer M 17 was a heavy trench mortar used by Austria-Hungary in World War I. It was developed by Skoda as an alternative to copying captured Italian 240 mm Trench Mortars. Skoda presented two versions, one with a rigid barrel, and the other with a recoil system. The former was chosen as it was simpler to produce.
