I found this link in Germany:
http://german-vintage-guitar.com/ind...cPath=9&page=3
Exact same guitar, not sure if usefull info though, my old OS only reads the page partially. Will search some more and post further links inhere.
Some more info, this model but a 12 string was played by John Lenon, it was called Framus 12-string Hootenanny 5/024. After browsing 20 Google picture pages in Germany I found that the guitar was also known under the apropiate modelname 'Texan', at least in poduction till 1973 or so.
Dieter Hopf may have been the luthier who build them as I found one picture of his guitars which looked remarkedly simmilar.
The brand is now owned by Warwick guitars.
Sorry I couldn't find out more, nothing had that same headstock as yours, they were all plain.
