Couldn't find much about this beautiful Hoyer Jazz Guitar... It looks like a later, less luxurious and electrified (might be a modification) version of the famous 50s Herr im Frack (Gentleman in Tuxedo). It's noticeable for the rare mix of two non-F F-holes and a round soundhole - some Hoyer of the time even had 18 soundholes all around the table!
