Yeah, lots of those have turned up in Toronto over the years. Even owned one once. They're simply "Lute shaped" guitars, and I guess there was a market for them. The most recent onces I've seen appear to be about 80 years old and are European (German?) made. The biggest problem seems to be that none of them were braced very well, and even with nylon strings, there's a lot of sound-board warpage.
