One of my vices is vises, Rock Island

McSherry Auctions

Here's a vise found on the McSherry Auction site, currently sitting at a dollar, halfways across the country unfortunately, shipping isn't practical... The only identification is the patent date which led me to patent # 1,111,103 which identifies the device as (probably) Rock Island and covers the method of presetting the jaw opening, a pin sliding through the body. 

Thanks, John!
