A RARE one - A 4” jaw, 40lb “Harper’s All-Angle Vise”.
Very rarely do I come up empty in my research of a vise, but that’s exactly where I’m at on this one. No ads, no newspaper references…zilch. If any of you have any info, please share!
I only know of two others in existence - one that
@KMScott shared a couple Facebook listing pictures of several years ago and another owned by a friend of mine. Both have features that vary slightly from the others. Given the overall condition, hardware, and style of the vise, I would guesstimate its manufacture date sometime in the 50s or 60s.
