Good example to learn from though. The seller’s description is ironically telling: “ Presented for your consideration is this Vintage Case Tested XX 1920-1940 Stag Copperhead trapper Jumbo Jack Pocket Knife. Beautiful piece. So many subtleties that I am am having a hard time locating another example exactly just like this one to compare it to. Rare, hard to find.”.

So how many incorrect things do you see?
