I just acquired one of these today. It is called a ukelin as it is half violin and half ukelele, although looks more like a dulcimer than anything else. Production was stopped in 1964, so they aren't that easy to come by. Mine went for 40 bucks in the 1930's and still has the owners manual, song books, tuning key, and replacement parts catalogue (strings were a quarter each). I am really excited to learn how to make creepy noises on it (songs, as noted by George Carlin, are about a million too many), but first I need to get a new violin bow. I'll bring it next time I make it to Atlanta and we can record some sound waves off it.
