It's a Gemini mini bike. Puma had one that was basically identical. Dad grew up on one of these. His dad and brother put one together. You ordered them as a mail order kit and put on your own engine. Dad still has his and is wanting to restore it. I ran across this one on craigslist Friday night and dad had me go get it. So off I went from Seward, NE to Creston IA. 160 miles one way. It's in pretty good shape really. Tank has some rust but only surface. Foot pegs are missing and 1 mount is broken. Right brake perch is busted. Centrifugal clutch and cover is missing. Otherwise it's complete. I honestly think we'll be able to get both of them going again.
Sorry no pictures of the original my dad has. It's orange in color but for the life of me I cannot find a picture of it!
