Re: Selmer Model 26-???
no no no, not modele 26. Selmer NY was another usa stencil, its probably a conn or a buescher, possibly a martin or king. What kind of sax is it? If it is a tenor or bari, in good shape, I wouldn't flinch. though an alto, I would seriously have to analyze the condition of my C melody and the condition of the NY. If the overhaul means only pads, it might be worth it, if not, not.
A complete overhaul for an alto will run no less than 600.
