Vintage KO Friction Motor Super Jet Ray Gun with Box Tin Litho JAPAN Noise Maker

This ray gun is super cool! Clear casing allows you to see the workings inside as the gears whirl and lots of "ray gun noise" is made. This is not the one that sparks, by the way. It has signs of a child's playing with it, trigger and handle has a little tarnish. Litho tin print is brightly colored. Box has aged, of course, but no missing pieces or tears. Please review photos carefully. Thanks for checking it out!
