I bought this vise from an engineering student when I was in College, its been with me for over 20 years and have used it lovingly. Its got true rotary with adjustable tension, hardened jaws, and pedestal base. Its not a Renzetti, but he actually machined this vise with the same dimensions as the traveler vise. I've tied down to size 24 Tricos all the way to 1/0 Salmon patterns successfully with this vise. $65 + shipping and paypal.
