Dell's Big "D" Astronaut No. 605 yo-yo is a hard to find model nowadays. Its profile is very similar to the Dell's Big "D" Fireball No. 606 that glowed in the dark. In fact, the stamp on both models is identical except for the name used: one is stamped Astronaut and the other Fireball. The Astronaut was also very similar to the profile of Duncan's wooden domed Satellite and their bi-colored Satellite yo-yo models, each from around the same time period.
The Dell Astronaut was made with plastic satellite "rings" and plastic domed body halves; fixed metal axle. Gold hot stamped design on the face of one halve. It's unknown if there were other color combinations besides the black-and-white version in this exhibit.
A carded version of this Dell model – if such a version exists, and there's no reason to believe there wasn't because all other Dell yo-yo models were carded – is elusive.
