I wouldn't think the SEC would be interested in someone's attempt to take over an OTC ticker. Especially one that has been delinquent in filing for the past 10 years.
I don't believe there's a need to contact Antonio, either. From all the instances I've experienced, applying for custodianship is used for taking over a shell.
This board would be the best place I could think of for the questions you have and the guidance you seek.
