PISTOLA INTERPLANETARIA - MAKER? - SPAIN?

This is a Spanish version of the American Super-Site Magic Bullet space gun. Hard plastic space gun with a telescopic sight running the full length of the gun. Click action with a captive reciprocating bullet that peeps out of the barrel when the trigger is pulled. Marked Interplanetario Automatico Telescopio. The telescopic sight is just a tube and there is no whistle built into the handle, though the mouthpiece is still evident. Gold plastic. Maker? Possibly PLOMBEL

Also shown (below) is a version of the gun with a different firing mechanism. It would appear that the gun is cocked by pulling the plunger at the back of the gun. Details? Name?
