Appears to be a "Graves" faceter with extra discs. I would be interested in buying it. Missoula is not that far from Swift Current, Saskatchewan where I live. e-mail me if you decide to sell. ...Rick... rickn1@sasktel.net
Ture it has value or worth and finding the right people to buy it may not be as hard as one would belive.. I may self have found rock tumblers via flea markets etc.. and your items would be listed in the same catigory.. I'f your not intending to use the items yourself then locate local gem and mineral clubs for a donation or even dontate to a local school/community collage.
