The Federal Police in Germany still use the EC120 at Sanck Augustin [near Bonn] - but only in the training role. They replaced earlier Alouette's and do not carry operational equipment.
France still has AS350s home and abroad. Being replaced as we speak but a way to go yet.
There are singles in operational use elsewhere in Europe but I think its fair to say they are mainly police use of military machines [i.e. Denmark [AS350] and perhaps Switzerland but they have now moved on from the Alouette to the EC635]. There are MD500s in the East .... Hungary, and depending how pedantic you are about the police role as opposed to a real POLICE sticker.... Italy MD500, the former Yugoslav countries B206, Malta....Alouette III...
There is still some way to go yet before Europe becomes 100% twin.
