That thing is sold on BudK for about $120 or so. Seen it in their catalog. Nonfunctional except for the machete blade. Even if it is a live fire capable piece, loading and disassembly would be a PITA. With that knife blade there, the loading lever is completely useless and you would have to load the cylinder on a table or a rock with a dowel and a mallet. And as Colt open-tops are held together by the threads at the rear of the central pin (arbor) alone, with no solid topstraps or frame hinges, if one was to actually use the "bayonet" in combat, ONE good smack on that blade will bend the arbor or dislocate it just enough that the cylinder will be locked up and unable to turn once the hammer is attempted to be worked again.
