It seems large rodents have eaten the main and secondary armament of this poor Italian Coast Defence Ship!
I know she was used later as a floating AA battery at Tobruk - for which her AA armament was altered (but the original 10" and 7.5" were left in situ and contributed to the defence of the port).
Is this a graphic bug (possibly indicated by the floating AA gun over the missing forward 10" turret)?
