Reminds me of the story of a trombone player in a major symphony who spotted a baritone horn case on top of a dumpster outside the symphony hall. He opened it and found a beautiful 1930's Conn baritone in perfect condition. He took it to the orchestra manager and asked if he knew anything about it, and it turned out it had been set aside and forgotten about years ago in an attic that was then being renovated, and the construction workers must have just tossed the case without even opening it. I believe he now plays that very horn in the few orchestral pieces that call for it (one of Mahler's symphonies, a few works by modern British composers, and not much else).
