I'm new to the Blacksmith scene but I've been looking at post vises for some time and have seen plenty of three and four inchers. This was in a shop I visited last weekend. That wire brush on top is a standard size. The jaws were as long as from my wrist to finger tips.... every bit of eight inches . The pic doesn't do it justice. It was cleaned and polished like the silverware in your wife's kitchen. 

And on ever bench I have a 6" postvise on I also have a 4" on the other end as it's faster and easier to use on certain projects, especially if you are closing it with your knee.

Looks like a modern screw in that big old timer. 

 

I recently missed out on a really nice 8" post vise listed on Craigslist for $80. There are some still floating around out there for good prices. I have an Iron City that is around 6" that I use now.

I have an 8.5" no name and just picked up an 8" Columbian. Sadly around here the larger vises anything over 5.5" are tough to come by as are larger anvils over about 250lbs..  Vises of larger size are going for big money.. 

 

The one I have is maybe the twin in the picture as they are the same MFG..   Mine is an older die forged Wrought iron.. I can't get the picture to be the correct orientation.. 

I was spoiled working on this guy for 15 years. I need another 8" er. Have you got a spare 8" lying around you'd part with?

When I make my 10" I might part with 1 of them but that won't happen for sometime..
