Above is only a partial list. Just about everybody made them. You also want to consider one the mid-1980s proportional models (24" front wheel with 700C rear wheel). Typically they were mid-range models, featuring better tubing and components than the Junior 24" models, but with silmilar standover height as they were designed for short adult females. They're commonly referred to a 'Terry' bicycles, after the designer/brand who popularized them.
