Don't know much about this knife.  It has me stumped and I enjoy researching cutlery history.  It does look factory made to me.  It also looks USA made.  Blades are carbon steel (tested it on the spine of the main blade).  My guess is that it's 80s or 90s but it's just a guess.  It's a well made knife with beautiful bone covers.  Shield is glued.  Might be a very tight hairline crack on the at the front left pin.  Hard to see.  The mechanics are great with very strong pull.  Blades have an "as ground" finish and have been sharpened.
