I think I found my vise-

Although it's 120 plus shipping, it's a Palmgren 4" vise, model #MVS40. Normally, it retails for 166 but Enco has it for ~120 before shipping. If I can get some confirmation from someone who is knowledgeable about these products, I will press the order button now.
Edit- Here is the link to Palmgren's site. Note the manufacturer numbers are the same on both the Enco and Palmgren pages.
