Finnish aviation museum, at Helsinki-Vantaa airport area, 2 km. from the terminal.
Long video but those who are interested in old airplanes may find this long video interesting/useful. Helsinki is however rather unknown city for many and Helsinki/Finland is far north and on the outskirts of Europe. The museum has also library - if you need information about aviation history in Finland I am sure that their librarian/information specialist can help you.
