Can anyone identify this guitar or does anyone know anything about it?

So it seems like otto gläsel was a store in germany that sold soli/hanika guitars with their own label and logo, but I have no idea if this is a hanika or if they did this with other guitars too. I couldn't find the model online.

Update: I have emailed the company and they have confirmed that hanika built their guitars in the sixties and seventies. The amazing gentleman who responded to me said that this is closest to their models from the fifties, worth about 500-700 DM at the time. The top seems to be solid spruce, the sides and back rosewood.

If you're in germany I would totally recommend purchasing an instrument from them, they were incredibly experienced and kind, and this guitar –despite 70 years of wear– looks and sounds gorgeous.

It seems to be a pretty down to earth operation, with not too many employees. Check them out, and check out flea markets in your area. Thanks to @morgunkorn@discuss.tchncs.de for all the help.
