OK, I bought this thing shortly after I started this thread. Finally took some photos while sitting in my vehicle, bored out of my mind one night at a jobsite. Authentic or not, it certainly has a "cool factor" to it.

Without taking the handles off, it definitely looks to have been "created" by mating a bolo with a bayonet. Whether it was a field mod by a unit armorer, or done by some Bubba, who knows? It looks like it was done well, and a long time ago. The stitched rawhide sheath inside the scabbard was a surprise, wasn't expecting that! The canvas pulled off when I went to pull the knife out, I suppose I should reglue it. Or not.

Opinions? Sorry for all the photos, but hey, y'all LOVE photos, right?
