Wondered if any of you have seen a clamp vise quite like this. $1 yard sale item. The jaws will only open up to about 5/`16" and it will allow something with a depth of maybe 7-8" to go down into it. The wing nut allows it to pivot 90 degrees from vertical to horizontal, but I'm still curious what this item was designed to do.
TIA
