I went with this old through bolt vise after seeing the bench had 2 through bolts on it in the past. I knew I had one that I got last year at an auction and found it, I wish I knew who made this vise, all there is No. 7 on the side. It is a very well built vise and all I did to it was clean the screw and applied new grease and now I can open and close it with a feather it is that good. I will require a larger vise and when I have time over the winter I will give this Parker 66 the attention it needs before the bench is its new home. The bench is big enough for two vises and I think it NEEDS two.
