Found this gem laying in the barn yesterday afternoon. I've probably walked passed it and tripped over it 100 times in my life but never paid much attention to it. That is until I joined GJ and got an obsession for anything and everything old and made in USA. Anyway, after reading this thread last night I decided to pull it out and get some more information. According to [URL="http://www.practicalmachinist.com/vb/1093596-post27.html" ]this[/URL] it's a Parker Eclipse Machinists Vise and retailed for $20. It will probably be awhile before I get it cleaned up and in use, as my shop is still sitting in crates on the ground.
