One of my vices is vise/anvils, an abused Rock Island Manufacturing anvil/vise

   Interesting and very abused Rock Island Manufacturing anvil/vise. It looks like there is a quick adjust feature, in that the screw block slides on the same track that the jaw does, that track appears to have been replaced. The anvil portion has seen a lot of use, and it appears someone has broken and welded the jaw to the anvil. It's for sale in Winnipeg here.
