OHTA (K)

 
 Ohta, K, produced few space toys and, to my knowledge, just two saucers based on one pressing.
 
Spacecraft Jupiter, with Spark
 
A thin saucer with a large central dome and a spark window. The one notable feature of this saucer is the oversize key which hits the fground as it turns and alters the direction of movement. It's a cheap alternative to a more complex mechanism.
 
 
Spacecraft Jupiter - Jupitep
 
Yes, a spelling error. The ship's the same as the one above, though, with just a change of livery.
