Guitar Info

I'm doubtful, on one hand this travel guitar looks definitely handmade - its fretless fingerboard over the body/neck junction could come from a typically east-german hollow-body Schlaggitarre and the electronics are limited to pickups and Flying V-style jack output... On the other hand I've seen this body shape before - though I can't remember where...

So what do you think: is it an awkward retrofit, a crude copy, a Frankenstein, a steampunk prototype?
