Austro Hungarian gun ID

[fert]

Hello,
Anyone can help me to ID this gun?
pic from Werk Busa Grande 1915


I was thinking about a double-barreled 25mm, but I can't find any information about it.

I exclude Nordenfeld gun 25x95

Could be this 25x120?


thanks in advance for your help

25x120 :

Re copy 1922 (...) original 25mm Skoda Marine , Insert barrel + ammo (drawing system : 132Km 24)

I think the gun in the fortification is a regular MG (of some sort) mounted in a an armoured housing. This type of housing (or similar) was used in some fort positions to protect the MG from shrapnel, splinters, and bullets.

Possibly an 8mm Shwarzlose M.7/12 ?? or Skoda M1909 ??

I think it's a Montigny Mitrailleuse, adopted by AH army in 1869

That's one had never heard of.

any pic of the gun?
did the gun originally designed as anti torpedo boat and when obsolete used as insert barrel?

AH navy bought some 25mm Palmkranz-Nordenfeld, could it be chambered for 25x120?

it seems the model of cases is 25mm M 03, or it's not referred to the year of adoption?
the oldest 20x120 I've seen 1904 made
regards

25.4 mm Palmkranz-Nordenfeld, 25,4x94R unfortunately not for the 25 x120Rmm .
I don't have any weapons (drawing or photo) for the 25x 120 cartridge (only a drawing of the cartridge case)
