The wonderful thing about Eukilines is Eukilines are wonderful things. (Probably.)

But the most wonderful thing about Eukilines is... this is the only one. (Apparently.) I spotted it for sale on another page, was intrigued by the name and googled, only to find several different 'for sale' listings for the same instrument - and nothing else at all.

What is it? What's it related to? What would you do with it? (One of the other 'for sale' listings says that the bow is missing, so that's a clue.)
