I have a parker vice, the swivel works great. Mine has one of the swivel locking bolts.
One thing I will caution you on, is I've been told that these vises are not to be used as presses. The week link is the nut I was told, if you use them as a press you can break the nut. I broke a Wilton doing that, the jaw casting broke, so I am a little cautious after receiving the warning from 2 people. Just passing on what I was told.
Enjoy that vise... Does yours have the round ended screw with the tensioning screw in it so the handle can stay put? I love that feature... Later models didn't have them. oops, just noticed yours is not the rounded end, but does look like it has the tensioning screw.
