Needed: Fraggle Rock Guitar and/or Banjo

[heytherejeffro]

I am in desperate need of one of those old Fraggle Guitars or Banjos (seen here: http://www.muppetcentral.com/collectibles/fraggles/toys.shtml).
My girlfriend often laments about how her father threw hers out when she was a little girl, and how it was her favorite toy ever. I would do anything to get a hold of one of these for her.
Does anyone here know how I could get a hold of one?

Thank you!
Jeffro
