this is the typical horn that gives this kind of headache when one discovers it in the attic and that it needs an overhaul. What am I going to do with it?
they are worth a couplde of hundreds not overhauled and more and less, or only marginally more, the same, if perfectly playing
My advise is sell it an put whatever you make (200?) towards buying a functional saxophone. What most probably will happen is that a technician will buy it, restore it and sell it for a little more that the overhaul would have costed the original owner.
I occasionally buy horns for selling and I don’t buy these because the cost of an overhaul is not far from the price that I would get if I would sell it.
I strongly disagree with the advise to buy a generic Chinese saxophone ( I would buy a Bauhaus Walstein though) . Whatever amount of money that you have available would be better spent in buying a Vito-leblanc, a Yamaha,(or Vito-Yamaha) an Orsi or any other horn that the market doesn’t like too much but that is a good player (and that includes a Bundy but not the II which I intensely dislike ) rather than fixing this horn.
