NABF lightweight title

[scartissue]

I see on the history of the NABF championship boxrec has Jimmy Robertson as lightweight champ having won it from Ruben Navarro. But then the next championship activity is Esteban DeJesus and Ray Lampkin. But on July 6, 1972 Robertson lost his lightweight title to Chango Carmona of Mexico. I believe this needs to be added.
