Right from an estate sale....
 
Vintage HARD TO FIND knife made by Western.  Marked BOULDER CO. USA.  I believe this was made in the 1950's but could be earlier.   I dont believe that the sheath is original to the knife but they do work well together.  The sheath looks to be newer.
 
Condition:  The knife has some signs of age as it is from the 1950's.  No broken parts of the blade and is still sharp.  The stacked leather handle has some light wear also but no major issues.  SEE PICTURES AS THEY ARE PART OF THE DESCRIPTION.  The sheath is in good shape and its snap still works.
 
The total length of the knife is 8".  The blade is 4 1/4" long.
