I picked it up this evening. On the side under where it says Craftsman, is also a raised cast in number "51854". Underneath is the number 76653-03
Be honest with you, this is one of those tools that proves not all things "made in the USA" are top quality. This vice is not a complete POS but it's pretty cheap compared to my Wilton. Then again, that's probably not a fair comparison either?
It should work for what I need it for and was cheap and not Chinese so I guess I won't complain.
Anyway if any of you have any more info about it, I'd appreciate it. My guess is this vice is around 15 years old?
