I can't be of any help but found your post and thought you might be able to help me. I just picked up a Rokkomann acoustic that is the strangest thing I've ever seen. It looks exactly like a classical guitar except the bridge is for a steel string acoustic. The 12th fret is at the top of the body, the size of the body is very OM like and the fret board is wide (not as wide as your typical classical). All is says inside is No. TF-60 and Year (but no specific year marked). Were you able to find out anything about yours and if so, can you give me any help.

Thanks,
Greg
