Generic Merchant "A". It's heavily based on a ship that Subsim user Xeidos2 was going to include in his now-defunct WWI U-Boat game:

This vessel will be very common, since practically all seafaring nations used small steamers like this one around the outbreak of the war. The text amidships is correct on both sides of the hull, since it is printed on a modified deckhouse for the parent unit (Liberty Ship).
I'd like to try a "Warspite or a WWi light cruiser but I'm still trying to learn how to model warships properly. The cruiser I built earlier had some inaccuracies with the rigging, etc; these need to be fixed before it's released.
