Description
Design 192 was a modified, lengthened version of the previous Design 191 offered to Argentina:
www.deviantart.com/tzoli/art/V…
But instead of a very mixed main battery, this time a single caliber the 10" or 254mm was chosen. The extra 13m length was surely meant to mount the 12 cannons in single turrets on the sides as the basic Lord Nelson Hull could accept such number of weaponry just fine in twin turrets in hexagonal arrangement! None the less while the design shows the signs of an all big gun dreadnought battleship the Argentinian Navy was displeased with the design and somewhat later Vickers offered a different battleship with 8x 12" cannons and 4" secondaries (Probably in a 2x2, 4x1 arrangement)
This designs good points were the single caliber weaponry and the smaller power plant because of the much better length to beam ratio compared with Design 191. The reduction in main weapon caliber and reduced secondary guns number allowed the increase of the belt armour by an inch from 8 to 9inches and the displacement only risen just 500tons!
The design had the following characteristics:
Dimensions: 138,7 (pp) 148,5m (wl) x 22,55 x 7,31m
Displacement: 12.500tons (standard)
Armour: 25mm Deck, 229mm Belt
Engines: 15.000shp, Vertical Triple Expansion Engines, 2 shafts
Speed: 37km/h (20knots)
Armaments:
2x2,8x1 10"/50 (254mm/50) Vickers Mk C Guns,
14x1 3"/50 (76mm/50) Vickers Mk A Guns,
4x1 457mm Underwater Torpedo Tubes

This actually might have been a more effective design than #191 due to its uniform main battery; no question of 'are those 12" shell splashes? 8"? 7"?' (I used USN Connecticut class as example here, the difficulty distinguishing shell splashes was of course one reason all-big-gun dreadnoughts came to be favored).

Yes, though Friedman's note of "In 1906 news emerged from Brazil of the dreadnought project armed
with 10in guns. Argentina was offered a similar ship, Design 192.34 The
Argentines were clearly not pleased with it, because in May 1906 Vickers
offered them Design 211, armed with eight 12in and twenty 4in QF (plus
two torpedo tubes) on 14,200 tons."
And indeed on the basic Lord Nelson hull you can mount 12x 10" just fine, you can even squeeze another twin per side if you must for a 10 gun broadside but 8-9 is acceptable on that hull no need for a longer hull.

Agree, at this point in time range-finding was difficult enough without trying to distinguish between 12-inch and 7.5-inch shell splashes. Among the worst were the USN's Connecticut and Virginia classes with 12-inch, 8-inch and 7-inch and the RN's King Edward VII's with 12-inch, 9.2-inch and 6-inch. Indeed all the intermediate dreadnoughts (those with a heavy intermediate battery between 7.5-inch and 10-inch guns) meant figuring what splash belonged to which gun was just about impossible.
