I recently bought an Otwin half size steel string acoustic at a flea market in Zurich, i had never heard of them either, i had to do some work on it, the bridge had to be removed and re-glued, also i had to try and lower the action but it has no truss rod, once these problems were solved i had the sweetest little acoustic that i've had for years, really great sound for such a small guitar and it serves fine for my camp fire instrument.
