Cutter my boss has an identical vise and he says it's pinned. He rebuilt his also. It may be difficult to find the pin.

Cutter, well, here's what I found out. There is a pin on each side approximately in the area shown, symmetrically located. They may be hard to find, so Bruce suggests polishing the area to shiney metal and using a cotton swab with nitric acid. The pin should show up. The nut is shaped as shown, but the nut is cast and can be broken with excessive force. (Bruce told me not to ask how he knew!)
The nut, at last count, costs $85!



P.S. forgot to mention - Bruce says the two pins are only nut retention devices. They don't take any rotational loads as the vise is tightened. The back flange of the nut is machined to engage the bore to provide anti-rotation.

Thanks so much OP. You are indeed a princely fellow.

I had found an exploded view of a similar model on the Grainger site but as you can see, it leaves a little to the imagination. Last time I had the vise on the ground & let it dry off well, I saw a little dimple that made me wonder if there might be pins involved. This drawing confirmed that (assuming the design holds true for older models) but I was still not sure how far back on the cone to expect to find them. I got a little daylight left today so I think I'll go hoist it up and take a look.
