He is a beauty His face does look a bit MC to me. He would be called a dlh with as you said American shorthair ancestry and possible forest cat ancestry too maybe.
He is beautiful! I agree with the above. He is considered black and white DLH or domestic long hair. One way to know is tufts of hair between his toes and a bushy tail!
Seems to be long haired. The toe tufts and tail are generally the deciding factors. Looking closely at the last pic, I think he does have toe tufts, but none of the pix show his tail. He has a nice ruff too.
