A close rendering of the original Ger/CB/1911 design

I had originally conceived of the Ger/CB/1911 as having a 140,000 SHP machinery, producing 40 SHP/ton of machinery weight. The armament was modest, with 6-12in/50 and 8-6in/50 guns. The side armour was inclined at 20 degrees and there were two armoured decks: the upper was 5in and the lower was 3in. The torpedo bulkhead was 2in, while the turrets and barbettes were 8in at the thickest, while the turrets had 6in sides, top, and rear. This is a photograph of one of the ships:
