Cruiser Grau in 1933, with a Vought O2U observation seaplane, without catapult.
Cruiser Bolognesi in 1942, with an odd camouflage pattern and a 3 inch AA gun of japanese origin.
Cruiser Grau after the last modernization in 1944, a tripod foremast was added, with an italian optical rangefinder, new superstructures, 7 AA 20 mm automatic guns, doble depth charge racks, and also a "Y" depth charge mortar. The pair served in this way until replacement by Crown Colony cruisers in the late 50s.
