I see Battlefield Berlin has them, but their shipping, at least to Sweden, is atrocious. I think they only use DHL.
BfB sends smaller orders by letter mail. I don't think I've paid that full 15e DHL cost more than once, and that was for a real boatload of stuff. If it's only a standard flat box of railroad plastics, it should be far less.
On the other hand, brief browsing at BfB usually reveals that you actually want a boatload of assorted goods.
