Hi again
The following is based on an original plan published on dreadnoughtproject.org. It is labeled 'Guertelpanzerkreuzer' but lacks any further documentation except a pencilled date (1893). The ship seems to be armed with four 240/30 or 240/35 guns, eight 150/35 guns and eight 88/35 guns and has a french-style very narrow full-length belt which would certainly have been fully submerged at full load. It probably was a preliminary design eventually leading to the Fürst Bismarck, Germany's first armoured cruiser. Dating to 1893, it could probably have been completed in 1896, in which case it would be painted in the old-style black-white-buff livery...
... or later, in which case the paintwork would be the 1896-grey which remained standard for German ships till 1945.
Greetings
