Hello Alan,
I think that the collection of the "Museum für Völkerkunde Dresden" is very good and interesting. Unfortunately I never have been there (it's far away from my home city). Here is a link (german language) but there is as well a contact given in down so you can write a mail to Mrs. Martin to get some informations.
