Armour

Per Lyon, Hugh; Moore, John E (1978). The Encyclopedia of the World's Warships. London: Salamander Books. ISBN 051722478X., p. 169:

• side
  • belt: 6-8" (152–203 mm)
  • ends: 3" (76mm)
• deck
  • upper: 1.5" (38mm)
  • lower: .75" (19mm) in 1912; increased to .75–4.75" (19-120mm) in 1929–31 reconstruction
• main turrets: 3–9" (76-229mm) in 1912; increased to 6–9" (153–229mm) in 1929-31 reconstruction
• barbettes: 10" (254mm); increased to 11" (280mm) in 1929-31 reconstruction
• casemates: 6" (152mm)

Deck, magazine and turret armour were improved during 1929 refit.

Per Ireland, Bernard (1996). Jane's Battleships of the 20th Century. London: HarperCollins. ISBN 0-00-470997-7., p. 70:

• bulkheads: up to 9"
• decks: 2.75" (note possbile variance from above)

The 8" main belt was 12" deep, extending from "A" to "Y" barbettes. 6" upper belt extended up to forecastle deck; closed by bulkheads fore and aft to form central citadel.

Weight of armour was increased from 6,500 t to over 10,000 t in refits.

From Jane's Fighting Ships of World War I, originally published 1919 by Jane's Publishing Company; facsimile republished 1990 by Studio Editions, London, ISBN 1 85170 378 0, p. 165:

• armour is stated to be Krupp (!);
• 6" upper belt (battery) extends from "A" turret to "X" turret;
• 8" main belt extends from aft end of "B" barbette to aft of "X" barbette;
• 6" side armout extends fore of 8" belt to fore end of "A" barbette and to fore end of "Y" barbettes; barbettes have heavier armour;
• 3-4" end armour to 40' of bow and 33' from stern
• 10" on conning tower;
• 9" on turrets
• 2.5" deck

From Jane's Fighting Ships of World War II, originally published 1946–47 by Jane's Publishing Company; facsimile republished 1989 by Bracken Books, London, ISBN 1 85170 194 X, p. 185:

• armour is Krupp;
• main belt is 12'5" deep and 8" thick; extends from foremost to aftmost barbettes;
• diagonal bulkheads of 5–6" forward and 6–8" aft close main belt;
• upper belt is 6" thick, is between barbettes 1 and 3; extends up to forecastle deck;
• bulkheads of 6–9" fore and 6" aft close upper belt;
• additional 3" belt behind main belt, 2'6" deep;
• barbettes are 10";
• deck armour is stated to be 2.75" main, but during reconstruction 4" was added to decks, raising displacement by 3,000 tons;

It appears that vertical armour did not change during reconstructions; it's a little hard to determine as the broadside elevation drawing in 1919 edition is stated to be incorrect.

Bernard Ireland and Jane's agree, no surprise, as Ireland is based on Jane's.

Take a look at these sources on composition: [1] and [2], and search in each for Kongo. If you Google the author's name you will find a lot of information and also his qualifications. I'm not sure how to reconcile his statements with Jane's (that armour was Krupp).
