Originally listed as a skill three, it was also described as:
[as taken from the 1974 Estes catalog]
A spectacular model for display or flight. The most colorful and exciting Estes rocket ever!  Carefully detailed plastic wing pods, nose cone and tail cone. Two huge decal sheets.

[as taken from the 1980 Estes catalog]
Future version of a real interplanetary interceptor. Deep space exotic design makes it the pride of any modeler. Delivers excellent performance for really sensational flights. Dramatic 18” recovery, two full four color decal sheets, and quick release engine mount. Plus all die-cut balsa parts and detailed plastic wing pods, nose cone and tail cone.

I actually own two of these. Excelsior Rocketry has released some specific decals for this as well. You can make this a British interceptor, or a Canadian one!
