Here's the same thing I posted on the MEPD board...
Not buying it. The fifth and sixth teeth are non-existent. The original buck would have those CLEARLY defined. And, there are to few to no air holes. In order to pull what we've seen made from real molds, it has to have many airholes pre-drilled in all the traps, eyes, teeth, etc.
Another tell is that the teeth insets are tapered. those would/should be much deeper and not curved-in, an obvious tell of a recast as it's taking the shape of a pull that never trully takes the exact shape of such a small detail like the smaller teeth. That whole frown should be super sharp and the fifth and sixth teeth clear as day, but they're not there.
Nice forgery, though. It certainly looks old.
