The Sterling Super Ringmaster used the same wing as the original S1 Ringmaster. No LE sheeting, no top and bottom spars. The laser cut model from the link provided is not the same model as the Sterling Super Ringmaster.
From the Micro Scale Model Planes website:
Super Ringmaster Revisited by Bob Clauss
"...It was obvious that the model outline had to be exactly as Matt Kania had designed it for Sterling. However, we also wanted to incorporate the wing design I did for the S1A Ringmaster which builds on a flat building board resulting in a true wing that is not only stronger but lighter than the original."
The S1A Ringmaster had a different wing from the S1 and was released in the late 1980's in the Estes days. That wing had the C-tube LE and a different airfoil from the Sterling Ringmaster and Superringmaster.
The S1A Ringmaster is not OTS legal, and a Super Ringmaster that features that wing is a bastardization of the design. It may fly better than the original, but it is not a recreation of that design and should not be legal for any nostalgic events.

Ps: Congrats Matt on your win!
