Recently brought this 3" vise home. It has only one lonely "F" marking, and I have no idea who made it. It seems very well made, has 1/4-20 screws holding the removable jaws and bottom plate (with the "F"). The moveable jaw is attached to the acme screw with a very interesting (and new to me) fitting that ultimately transfers the pressure through a ball bearing. Is this familiar to anyone ?
Thanks for any info,
Dave
