I got a few of those Nordsee figures from a friend in Germany - IMO these figures are some of the best yet produced, with printing on the back as well as the front. Shame the helmet was not quite right. I also got the gameboard, but my German isn't quite up to understandign how to play. Clearly the pirate, soldier and ship's captain are racing around for treasure.
To clarify, the first 5 figures are probably direct ordered figures, with the not-quite-right helmet. They're not the same as the Nordsee figures - the belt, hair and head are different.
The separate helmets are better for conquistadores, and so earlymidnight might have got them through DS order, and offered them as replacements for Nordsee figures.
The single figure is a customised figure that someone's put together. When I started buying on eBay I bought a couple of customs, but quickly realised I could do the same thing myself cheaper, and now avoid them, though I see some sellers are making a nice little profit with customs.
