In doing so, he introduced an ERROR into the data, by calling the "Cream-colored" stripe on the Nose Cone "Natural Steel". "Natural Steel" is impossible, since the White, upper portion of the nose cone is Ceramic, while the lower Brown section is Phenolic.
I believe that the "Cream-colored stripe" in the original 1974 Model Rocketeer data is actually a strip of masking tape, likely used when the two sections of the nose cone were bonded together.

That's a friggin' detailed correction! Someone should give an updated, and annotated article to Sport Rocketry so there is one true version. Maybe for 5-6 different rockets while you are at it.
