Hey Milspec, when you call Sunderlin again ask him WHERE he got the series information. Or how derived... because way to many thing are matching up way to closely.
I also want to add this... because some people may mistake being THOROUGH with some sort of attack, I am not attacking or making any claims that would infer that any of the fine people involved with these articles are up to anything nefarious. I am just trying to answer a question.
