I am sorry to say the Mekanisk Museum in Hørsholm no longer
exists.  It was run by the well-known collector Claes Friberg,
and was closed shortly after his death in 1996.

There is no museum in Denmark specialized in mechanical music.
There is a small association of mechanical music collectors,
Mekanisk Musik Forening, with only 50 members, including members
collecting phonographs, etc.
