you cannot blame our friends across the pond, Werner, it's a mess filling out the necessary documents... if they get the correct advice at all
I bought overseas twice, and had a friend travel with one bass to Switzerland and picked it up there and declared it at our beloved Customs Authorities, and travelled myself for the second acquisition... a far better alternative !
My very first Alembic is just around your block, Eva is in Leverkusen, to be precise. Please kick my *$$... so, there are chances that you will find a suitable bass within reasonable travel distance also...
here's crossing my fingers for you,
your Christian
