Thanks Bob.
I have great respect for card modellers. Many years ago I made a Wilhelmshaven card model of the Scharnhorst which took forever - the little Arado floatplane took weeks alone! Of course, even though I reinforced the hull with balsa internally, it warped and twisted out of shape. That kinda put me off the medium for life!
Chapeaux to those who bring 3D beauties out of flat card, though.
