PANDAY!!!  So you're the one that beat me out of this!! (along with others 

 ).  Yes, I had been comparing this to the Cato example and I came to the conclusion this was the same puppy.  
Also on the scabbard debate, I agree with Mabagani, and add another possiblility.  Early on many American collectors threw away scabbards. 

   Not must PI/Moro, but US Civil War and other historic pieces as well. 

   Thus, for example, it is so much more valuable to have a scabbard on a US Civil War foot officer's or staff officer's sword.
