Despite Moolah's claims, she never actually won the NWA World Women's title, instead breaking off from the NWA and defending her own "Women's World Championship" belt in various outlaw (non-NWA) promotions, and eventually the WWWF. She rarely defended the title against anyone other than her own students, and did not in fact have any 20+ or 30+ year reigns, often hotshotting her belt back and forth in this town or that promotion to get the locals talking. She arguably had an uninterrupted 8-year reign of a belt whose governing body was...herself.
I don't mean to speak ill of the dead, but Moolah was a master of embellishing her deeds and protecting her paycheck. There's nothing wrong with that, but it doesn't make you an NWA World Champion. "Women's Champion" or "Women's World Champion" is probably the correct name for her belt.
So should I delete rather the NWA belt or the WWWF version of the belt, as from what you are saying they seem the be the same thing?
I guess Moolah's World title went on to become the (W)WWF Women's World title, so it should probably be a WWWF belt. I don't know offhand if the NWA Women's title was active at this time or not.
