1969(?) R-700 twin-screw wrecker once owned by a friend.
237/5 speed - shown here in the 1993 Milesburg, PA bicentennial parade with me at the controls.
No power steering on this one, so the spectators had to get up and move their lawn chairs back so I could make it around the small-town street corners!
I really wish I had more / better pictures of this truck.
