I would suggest that Pauline's Gibson is worth taking to a luthier and having it repaired/set-up, but that Charmion's Montana mandolin isn't likely worth the effort or expense.

Charmion, HOWEVER...I assist at the instrument repair course at the Celtic College in Goderich and if you return in 2005, bring your Montana and maybe we can help you. We routinely tackle jobs that a business wouldn't, assuming there's time and the job is actually possible. There are three of us conducting walk-in repairs as well as course participant projects. Last August I can recall many different repairs to mandolins, violins, guitars, autoharp, harp, bouzouki, and misc side repairs to things like cases, stands, and other accessories. We take on expensive vintage instruments and entry level new instruments, so that the owner can PLAY.

Feel free to pm me if you need to know more, I may be able to help you.

Peace, Mooh.
