Assuming that you meant Kurt, the 3" and 4" versions have a casting
number
on the bottom of the vise. If yours has one, what is it?

I'll pull it off the mill as soon as I can. I know there is some numbers
there.

FWIW, my 4" Kurt has "D40 1" and "USA" in raised letters in a pocket on the
bottom of the vise. An older 6" Kurt would probably have something like
"D60".
