This spiffy little toy has a flashlight that changes colors via a small switch on top of the lens assembly. Flipping the switch to one side or the other moves either a green or red gel in front of the bulb. Simple and elegant, it's a system that -- with minor tweaks here and there -- pops up in many different ray guns. The Raydionic also makes a clicking noise when you pull the trigger.
This is definitely a rare toy, though another British company called Pifco will appropriate the body design a few years later for use in its Zeta Ray line of guns. More on those when I get around to them. For now, rejoice in the fact that I don't actually have much more to say about the Raydionic, and instead will leave you to admire the pictures.
