I was also going to point out that it was a claw.I'm no expert either, but there are several knife forums you can take a look at for research. What I do know is that the original T. Williams Smithfield went out of business circa 1938. Also, that is a claw...not a tooth.
Is what you have a real or replica, is for someone more educated on the subject. What you do have is a beautiful knife and someone is likely to find value in it.
This is too bad.Thank you!! Yes its nice but to be honest im not into knifes that much
