The Backbores available here in the Backbore Catalog are backbores that were duplicated from current mouthpieces.  These backbores are duplcations of a specific mouthpiece - mouthpieces vary from one to another, to a certain extent, even of the same brand and model - each backbore here is identified as the mouthpiece it was copied from, and labeled as specifically as possible. These are DIFFERENT than the FCB stock backbores.
