I have what has been described by a German Guitar site as a "high end" Franz Sandner Fasan guitar that is in almost original condition (it is missing the pick-guard). It was manufactured in the 1950s and is now more of a Collectors Item than a guitar for playing The owners of the website (German Vintage Guitar) have offered to buy the instrument from me - but I have no idea of its value and their policy is that I must come up with a price - they won't make me an offer. T'interweb has quite o lot of information on these guitars but I can find no suggestion of price. A picture of the guitar is attached.
