John Lorenz sent some photos of his Interstate Cadets. John says: "Robert, here are a couple photos of my Interstates as requested. They aren't award winners but they're mechanically solid and a hell of a lot of fun to fly even at our airfield elevation of 6500 ft here in central New Mexico. The S1B is a converted L6 with a O-320 Lycoming, the S1A has a C-90."
