I searched and found only one thread where this brand is referenced, and in that thread it seems to be a USA company, maybe one that Asia copied from.

I ask about this company because of this ad that I just read:
5 inch vise very heavy
I have been carrying this thing around for the past 20 to 30 years
never use this one .
I am not sure of the manufacturer
There is a tag on it I can make out what I think is Jefferson tool ? But
i am uncertain
It weights between 65 to 75 Lbs
it has a anvil on the back
knurled Jaws
Any info?
