I have found several TW-5's and 6's on-line for sale. They look to be tough old machines with little care, and the price reflects that. Surprisingly, if you look close, some do not have log lifts or multi-wedge lifts. You can tell partly by the number of hydraulic levers, even if the photos doesn't reveal it directly. Some have auto split valves which were standard on the TW-6, until a few years ago.
