For some reason the name "nun's horn" stuck in my mind. Maybe Danish. I swear I saw one in the Metropolitan Museum's musical instrument collection decades back, but after hours of Googling on both words and images, I am no closer to any answer. I did see the Octabass, which is allegedly the largest string instrument in the world and very cool in its own right.
Maybe I'm confabulating a memory. Maybe it's too idiosyncratic or one-of-a-kind to document. Maybe I'm just senile.
The Met's musical instrument's collection is closed for the forseeable future for restoration and re-curation, so it's a dead end.
However, let me offer you this very fine armadillo banjo picture in thanks. I KNOW I saw it in the same gallery.
