Behold ! I will conquer the galaxy with this...

Hey... wait a second... This is not a blaster... This is just a thingy that shoots... balls... yep... no darts... no laser beams or jolts of electricity or ... just baby blue balls... Guess Greedo used one of these in the Cantina scene... oh yes, he did shoot first... just with the wrong gun ! The rest is history...

Automatic Safety Gun, Japan, 1960's ?
