Hi Walter,
I think mine was earlier. He has a little plaque which he provides which has the number scribed on it. The little plaque is meant to be bradded into the wooden base.
Mine was with the original blunt jaws which I don't think he now makes. I have since gotten his midge jaws, the pro jaws and the Damascus ones. Mine has become something of a hybrid.
The photo below shows the original knuckle arm arrangement (in my hand in photo) that came with my original vise. Not sure how it functioned now as I now have what I take to be the standard configuration.
Perhaps those who purchased theirs earlier than my #80 could explain??
Bugsby or Walter or Ducksterman, perhaps you could clarify??
Thanks!
