I have a bunch of these and your papers are correct and the only thing you're missing is the tissue-like paper that was originally wrapped around the knife.
Boxes look right. I'd have to see a pic of the end to know for sure if they match mine.
Too bad that people often open these and then store it with the knife in the sheath......thus the heavy green stuff (verdigris).
Very nice knives, though.......and you can send them to Buck for a cleaning that will make them look like new for only $7 per knife.
