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 @[email protected] for all the help.
The company still exists and you can probably ask them directly: https://www.musik-glaesel.de/unser-team.html
Thank you so much! That is absolutely genius
Awesome! if you need me to help with the translation I will happily oblige
You are an absolute saint, but I know a fair amount of german, I'll manage. Thank you again, you absolutely rock <3
