"Treasure Island" sure looks right to me. Hope it's not stuck on that cardboard though. Would clean up just fine, imho.
I don't think there's much commercial value to finding old "lost" films, I'd be surprised if any of the DVD sales even recoup an expensive restoration, and suspect even a transfer to safety film is barely a breakeven venture. The bragging rights would be priceless though, as would giving back a bit of cinema history. If the story is true, he's a jackass.
