I also noticed this has a hole in the base. Opposite of the swivel lock. Any idea what that’s for? It doesn’t seem to be drilled? Appears to be original. Thanks!
Think I got a gem.
Vintage Prentiss Vise No 20
Couple questions. Is this the “graffiti logo”? Interesting mechanism to activate the swivel jaw base.
Any idea of the age?
How do I activate the swivel jaw? Does the top pin come out? All the way out? Spring loaded? Currently pretty stuck...
