This here's a little wheel thoughtfully provided by Skelly. It's four inches in diameter and in excellent condition. You can calculate you car's mileage with this, which sounds to me like a worthwhile endeavor. Skelly. It's power blended!
I noticed on the back that Slide-Chart Perrygraf Corp. is noted. I've seen that on other wheels. Well, guess what? They're still in the knowledge chart business with no sign of slowing down! There are many formats to chose from. Check out their website!
