Hey Bill,
If you were to find an original set of plans for this plane, they wouldn't help you much in the building. No full size views of anything. Fairly comprehensive written instructions with small illustrations to sort of let you know what they were talking about.
I built a lot of these back in the day. I flew them as a Jr. both for Combat and Stunt. Later I flew them in Open Slow Combat. Just so happens I have all the parts traced. Including the wooden control horns from a Sterling kit and the profile of the leading edge (solid, notched for rib spacing). As I am obviously sitting here at my computer, I'm not looking at the plans and I don't even know if I drew plans. I think I could put one together blind folded. I do have my own which is hanging on the wall and I could measure rib spacing etc off of it. Mine has a Johnson .35-S on it and I have flown it a few times but mostly it is just for the heck of it.
If you have any interest call me at 405-293-9276 or PM me.
Later, John
