You won't get anywhere contacting the AKC about an APBT, as the AKC does not recognize the American Pit Bull Terrier. CKC, or ADBA would be where you want to look.
I have not heard of the line you mentioned. As far as the terms "red nose" and the like, don't pay them much mind. People use the term "red nose" for any dog that has a red nose. I have two pits that are out of Ragin' Cajun (a red nose line), but both of mine have black noses (from the mothers side). I used to have a Colby line female, and she had a red nose.
Just be happy to have one of the best breeds of dog that there ever was!!
"To truly rescue an animal one has to provide long-term care that guarantees the animal's security for its natural life, because rescuing is more than removing an animal from a bad situation. Rescue involves restoring and preserving the animal's dignity for its natural life without stress, and this includes conserving the species as a whole for generations to come."
