If you have a sentimental attachment to this instrument I would still look into having it repaired. Have you ever heard the story of Bill Monroe's mandolin? Someone broke into his house and smashed it - and another mandolin - with a fire poker. And a repairman { the late Charlie Derrington } was still able to put them back together again. So don't give up until you've seen a superior repairperson who can give you a qualified opinion.
