I always thought Barbies #1-4 had heavy solid bodies and "TM" after her name on her backside. And #5 had hollow bodies with "R" in a circle after her name on her backside. Please help to un-confuse me. I now see vintage Barbies with solid heavy bodies, poodle bangs, and all other TM characteristics on a "R" body. I have one from my childhood which fits this situation and I KNOW I didn't switch any body parts.
