Fred: Skennerton lists 3 patterns of sword or Yataghan bayonets for Snider 2-band Sergeants rifles, engineers carbine, and artillery carbine. They're not all interchangeable. Since there are a lot more Sergeants rifles than the carbines, there are probably a lot more of the corresponding bayonets which probably limits their value. Personally I've payed $250 for a fairly good one.
