I've been trying to locate some decent 16th or 17th century wide brimmed felt hats for quite a while now, but almost all I can find are crappy costume pieces at 10 dollars or so. The only site selling what I think of as decent was this:

http://www.pyrate.org/captainkidd.html

But that store seems to be quite dead (no response to e-mails) and is located in the US (which would increase shipping costs).

Does anyone know other sources for decent-looking period hats, especially in Europe (though not necessarily so)?

Sweden based "Handelsgillet" has a selection of wool felt hats:

Thank you! That's at least one source close by. :)

The problem with that one seems to be that you'll have to find and fit all the extras for the hat separately (the belt around it etc.). Also, if I understand the site correctly they only carry sizes between 58 - 62, which would be ok for me (I'm a 62), but my wife would have to find another source (she's 54/55)... :/
