Yes, Dili. We have the following mounts/carriages for the 305mm Obice da 305/17:Dili wrote
Maybe the wheels of a siege mount being applied.
It appears a bit different than the Garrone siege mount http://www.italie1935-45.com/forum/view ... =34&t=3203
You can see here the Di Stefano mount: https://it.wikipedia.org/wiki/305/17
M1914 coastal turrets
Garrone M1915
Garrone M1916
Garrone M1917
De Stefano
but none of these matches with the mount/wheels of my photo.....
In the book "Le artiglieria del Regio Esercito nella Seconda Guerra Mondiale" of Filippo Cappellano, is cited a "Stampacchia" mount of 1918 but I have never seen any photo of this....
