The next pages in the Red Book are armouring schemes for the Ger/BB/1905

The very next page in the Red Book was the Ger/BB/1905 armouring scheme that I have previously published. The very next page after that is an alternate armouring scheme with less side armour and more deck armour (plus a quirky anti-torpedo protection scheme). In this scheme, there is no upper deck side armour and the main belt is 10in for 8ft and then tapers to 6in over another 8ft. For weight purposes, I reduced this to 12ft of 10in armour. The torpedo protection has two 1in bulkheads, apaced 6ft apart, with thinner bulkheads, not armoured, in between. The slopes were intended to be 3in and there are two armoured decks, the upper being 4in and the lower 2in. To accommodate this, the displacement is 22,700 tons normal. The armament is the usual 8-12in BLR and 12-4in QF guns. The speed is the originally intended 23 knots. I checked the original Blue Book specification for the Ger/BB/1905, and the armour basis was 10in and the displacement was 22,000 tons. This version works quite well in Springsharp:
