Vickers Export Design 580 for Argentina

I do not know much about this design apart that it was mentioned in Norman Friedman: British Cruisers of the Victorian Era, an 1912 cruiser proposal from Vickers for the Argentinian Navy most likely as escorts for the newly acquired Rivadavia class battleships. What makes this cruiser rather ordinary is the size and displacement stated in the book for it: 170,7m long (not sure if pp, wl or oa) and 9.000tons!!!! Displacement! Basically we have a heavy cruiser (Hawkins class) sized ship with the displacement of an Armoured Cruiser and the speed and armament of a light cruiser! Basically an Arethusa or Town class on steroids!

The design had these characteristics:
Dimensions: 170,69m (pp) x 17,07m
Displacement: 9.000ons (Standard)
Engines: 55.000shp Steam Turbines, 4 shafts
Speed: 50km/h (27knots)
Range unknown, probably around 14.000km at 33km/h (7500nm at 18knots)
Armour: unknown, on this tonnage, very thick armour for such ship could be installed, so probably around 203mm belt and 51mm deck
Armaments:
8x1 6"/50 (152mm/50) Vickers Mk R Guns,
10x1 4"/45 (102mm/45) Vickers Mk K Guns,
1x1 3"/45 (76mm/45) QF HA Mk II AA Guns,
2x2 533mm Torpedo Tubes
