Vickers Export Design 291 for Argentina

I've made this drawing as a sister design of 290, where I replaced the twin 12" wing turrets with 2-2 twin 10" ones otherwise the data is similar to the other uneven proposals.

The design had the following characteristics:
Dimensions: unknown probably 153,62 (pp) 162,25 (wl) x 24,38 x 7,62m
Displacement: unknown, around 20.000tons (standard)
Armour: unknown probably 38-42mm Deck, 229-254mm Belt
Engines: unknown around 21-24.000shp, steam turbines, 4 shafts
Speed: 39km/h (21knots)
Armaments:
2x3,1x2 12"/45 (305mm/45) Vickers Mk B Cannons,
4x2 10"/50 (254mm/50) Vickers Mk C Guns,
4x2 12x1 4,7"/50 (120mm/50) Vickers Mk A Guns,
4x1 457mm Underwater Torpedo Tubes
