I just found this little beast!
There are no marks of brand, the weight is pretty high, I used all my strenght to lift from ground to table
The conditions seems very good, there are two marks of carelessness, the threaded rod is in perfect shape.
My milling machine is tiny, I could Mount on the table for short time. I'm thinking about using this vise on the bench or a dedicated support as a normal big vise.
230mm width x 250 stroke
Any advice welcome
