This is a Professionally Made Factory Built Machinist Vise. It appears factory made but I see no markings on this vise. The jaws are 2" wide. Vise will open to 2". This has a swivel base with a cam lever lock. The interesting thing about this vise is that the center jaw is stationary and when you turn the handle the outside jaw moves. This is a very high quality vise in excellent condition.
Thanks for viewing, Please see pictures and ask questions as needed.
