Hello Aaron & all,

The Betterbee number was SR2 "old style" and sold for 8.50 U.S. in I believe
the 2000 or 2001  catalog. Possibly Bob S. has a few left. 1-800-632-3379
 I donated slated racks of both designs to a recent Midwestern Bee auction
but am sure slated racks of both designs could be found sitting on a few
beekeepers shelves gathering dust.
