I know that it can be difficult to tell if someone has the real thing or a repo from pics, but i have a chance to buy this at auction tomorrow and need some pro assistance on whether or not its worth buying, and possibly at what price. It has the "small" knife built into the sheath (see pics) so this may or may not be a big clue as to its origins, but I havent been able to figure it out. Really appreciate any input anyone may have. TY! Bruce C
