This is my first post vise. I gave 50 bucks for it down in Canton, TX. I have done quite a bit of research, but still need some help. I know it is missing the thrust washer for the front jaw, but the third and fourth picture is what the previous owner put in the thrust washers place?and of course the spring and the wedge for the mounting bracket. The mounting bracket has square headed nuts and bolts, which tells me there is a little age there? The pin that goes in the bottom for the jaws to move on is not a square headed nut and bolt like I've seen, it is a pin with a small slot in it? The screw threads seem to be in good shape, but maybe a small section broken off in the back. The screwbox had the thrust washer welded to it? Can someone give me any info on it?
