Have a whole batch of tiny Classic Space sets...
6809: XT-5 and Droid (’87) - An extremely simply hover-chair deal, but the droid is super cute
1557: Scooter (’86) - Probably one of the simplest recognizable spaceship designs you could make. Not sure if the hinged nose-cone had a purpose, or it was just the best way they had at the time to do the horizontal turn it needed.
6801: Moon Buggy (’81) - Odd name as I’d expect a buggy to have wheels, but the downward dish design is pretty cool.
6822: Space Digger (’81) - The neat claw on this will show up on a bigger set later...
