Super quality, dovetail slide, 4.25" machine vice.
A very decent engineering vice with a great smooth and strong feel to it. Will be a very good make but lost it's maker's marks. Jaws are 4.25" waide and 1 5/8" deep.
Rotating base is 10.25" x 7.5" at its widest. Is 4.25" tall, 3.25" tall without the rotating base that can be removed. Jaws can open to 3 5/16".
This vice is over 18Kg, so a sturdy piece of kit, and with the dovetail slide it's a quality engineering item.
