You found an old Sterling Super Ringmaster?? Wow!! I built 2- 3 Super Ringmasters and Ringmasters as a teenager. As I remember, the wings were the same size and construction was the same. I love the "boxy" lines of the fuselage. The part I didn't like was the method used to attach the cowl.. Clothing snaps, as I remember.
