Re: ID request!
Sorry, I'm 4 weeks late... It's definitely a Radius. 1993 only. [RV470 in the U.S.] IbanezDaemon's link to the wiki is correct.
Only two colors. The catalog shows a blue, but it's purple like Agent 540's [and mine]. The other is Tobacco like in the catalogs, and like the photo of the backside for that one on sale. The green-ish front might be from sun fading, perhaps? You can sort of see the tobacco color on the fringes. [Definitely see the original color on the back of the body.]
The Viper neck is quite nice, and the alder body... well, I'm not savvy enough to tell the difference between alder and basswood.
