also as a kid i remember owning two other wind up sprinters of jim nace and i believe johnny mackison. i can't seem to find them anymore but these were slightly different then the gripper sprint bandits but same size.
there was also Rick Hench, Glenn Fitzcharles, and my favorite Billy Crawford. They are under the "Road Champs" brand.
i know they were made in china and that there was some mistakes on the spelling of some of the things on the cars.
The Rick Hench car said "Menchcraft Racing Products" and Billy Crawford's car had "W. Haxelton, PA" as the location for Harry's U-Pull it.
