Another Project Sword model that comes with the Aoshima UFO Moonbase is the popular Moon Prospector.
Again, this is almost a perfect miniature of the larger Century 21 toy, and would have first appeared in Imai’s UFO Secret Doom Centre and UFO Space Science series.
This early Imai box artwork takes its inspiration from the illustration in the Sword Annual, using the same colours of the Prospector in the Annual painting rather than the colours of the actual toy, which is unsurprising as the artist would have probably used the Annual as reference material.
One small difference is the non-alignment of the outrigger stabilising wheels on the tiny model. Everything else, like the rails surrounding the body is fine, so the impression I get is that the model designer wanted to imply how the vehicle would steer.
Here you can see how small the model Moon Prospector is compared to the Century 21 toy.
Here's a comparison with the Spacex Prospector.
Next time it's the turn of the Scramble Bug
