Fresh barn find 1957 Mack B-61 THERMODYNE 6 speed tri plex trans single screw . The truck starts and runs great . It goes thru the gears . The only thing that I can mention is a small leak in the air tank that starts the truck. I Did not check lights and signals . But mechanically it is strong. Lots of local history with this MAC READ MY FEEDBACK AND BID WITH CONFIDENCE. NO RESERVE ON THIS ONE
