Tested, the tumbler powers on and still works as it should. It will need a new rubber drive belt as the original has perished and will not work without it. This unit is in the original box, with the original paperwork. it comes with everything you'd need to get started, the only bits that appear to really have been opened were the jewelery packs and even then most of it appears present. I would not expect the Jewelery glue to be any good either.
