I bought a buck 303 Stockman and I looked it up online and saw a lot of photos of this knife and in every one the two smaller blades were laid out opposite of what they are on mine. On mine the sheepsfoot is next to the main clip point with spey at the other end. In all the photos it's the other way around. I saw a photo that had a 301 that was laid out like mine but this one says 303. I dunno!
There is a very active Buck forum over on Bladeforums. Might be worth posting over there. Sorry that I can’t offer any more help than that.
