I am thinking of changing the color of my Frijole. Right now it's bright red. What other colors did Steen paint their Frijole frames-at least, when they were offered as complete kits? I have seen the ads where the kit looked like bare metal-but I have seen restored Frijoles that claim to be the original purple, or blue, or whatever. The Steen Taco history does not really have much info on colors. Thanks for any info.
