Pretty near impossible. You can try posting a WTB in the BST or Marketplace. Did Simpson even have a 2-band badger in the Somerset Era?
2-band and Super are two different things. A 2-band can be Super; I recently donated a 2-band Super Chubby 2 to the Contributors Drive.
2-band refers to a knot with an extra wide middle band; when set low enough, you won't see the bottom band at all. I think they tend to have bit more backbone that other grades.
