I remember seeing the Texas Tacos on the web around the early 2000's. At first they only made 22's. Later they started making a weird stand up scooter version with stickers all over it. At first the color was a lighter non metallic purple. I may have a few photos on my old computer. I don't know if they had any kind of serial numbers. At one time the company (name/rights, tooling, and inventory), was for sale on ebay for $50,000.
