Obice 305/17 modello 16 su affusto De Stefano

305 mm houfnice mod. 16 na lafetě typu De Stefano

Obice 305/17 modello 16 su affusto De Stefano
It was originally an Italian houfnici coastal defense developed for the carriage of the type Garrone. For the PSF, however, was also used with a gun of the type De Stefano. Some Italian materials, this weapon is referred to as moždíř, so can come across these two signs: Obice da 305/17 D. S. or: Mortaio da 305/17 D. With.

The letters "DS" are the abbreviation for lafetu type De Stefano. It was a universal lafetu suitable for transfer of large shipping and field works in the conditions of the PSF. It is argued that even the gun-carriage De Stefano was divided into three parts in the carriage of weapons on a greater distance, but with my knowledge rather demonstrates the use of two-piece sets. During the war served next to each other both types of lafet: Garrone and De Stefano. Out of the available resources can not determine exactly how much was which.

The war survived about 23 works and přepokládám that then there has been a single lafetaci weapons with třívozovou set.
