The scabbard does resemble those, but aren't they sewn up the back edge rather than the spine?  Also, the suspension strap is missing; is there a broken end of leather strap sticking out around the throat of the scabbard? 
Also, there is usually, If you're talking about what I think you're talking about (kodme), usually a hole that runs all the way thru the handle, thru which is passed a string of leather that heps keep the knife in the sheath (ie. a detente).  Is the dot we see such a hole?  It seems on the small side.
