Old Glory Miniatures stocks Blue Moon, at both
UK and
US stores; the US store is also has
West Wind.
Some of the
Steamforged Games Guild Ball range would suit.
Anima Tactics is now gone, but if you look through any old stock people may have, you may find something.
As for Terrain, Worldworks is currently inoperable, but some can be found at
http://paizo.com/store/byCompany/w/worldworksGames/downloads .
There is a lot missing from the range, though, including the Wildwood Grove set which is one of the most relevant to this board; and the prices are way higher.
Fat Dragon are still available, though.
Edit: Worldworks returns, though with many of the pre-Terrainlinx sets unavailable. Still, the range includes a Gothic-styled dungeon, undercrypt, pub and castle interiors, forsaken cathedral, graveyard, and old manor house.
Also, look up Dave Graffam Models on OneBookShelf or Ecardmodels, as they have many buildings for your European villages, though all hollow; and Grinning Skull Studios for decor.
