![]() So I'm thinking that dates my vise as being made before 1919. ![]() The 1919 catalog (catalog 6) no longer lists them. The last catalog I can find a No7 in is 1912, catalog 5. ![]() Those holes though I'm very sure were drilled. The rest has some smooth flat spots,especially along the casting seam, but also has a lot of imperfections. When I put a straight edge on it, the area within about a cm of the hole is completely flat and totally smooth. One thing in favor of the theory that it was taken off is the flatness of the bottom. Maybe it came like that, maybe someone just was really careful when the ground or cut that off and then sanded the bottom. You'd expect a bit of a chamfer at the top to prevent exactly that and help the screw start. The threads however come right to the top of the hole and a the topmost bit of the thread is chipped away. It may have been ground off so that it would sit on the bench, but if it was, someone did a really good job because it looks perfectly smooth, like it was never there. There seems to be a part of the bottom of others, a cinder of metal that goes into the base plate that it swivels on. There are two holes in the base but I think someone drilled those to hold it to a bench without the base plate it's supposed to swivel on. One had a straight threaded hole in the center of the base.
