A beautiful little "fish tail" v block with no name - certainly appears unused. It is tastefully signed by a previous owner on the side  The clamp, which mounts on the main body and the fish tail, needs a bolt which can be had at any hardware store. A really nice piece for fine small work. Thanks for looking - if you have a few minutes, I have many other tools listed, including other machinist tools and PARTS FROM A GERSTNER BOX (drawers, lid, etc.).
