He is almost certainly a moggie that happens to look a bit like a pedigree - though why a shorthair cat should look like a longhair breed is a bit of a mystery to me.
It's also worth remembering that NFCs, MC, British Shorthair and several other breeds are 'natural breeds' - selected from cats that evolved naturally to suit their environment. NFCs, MCs and Siberans all come from places with harsh winter climates, so they are large cats (large animals stay warm more easily), have thick winter coats witha nice big fluffly tail to use as a duvet, and have a lot less coat in summer as these are places where winter is cold and summer is warm to hot. So of course you get moggies that come along that look like they have some pedigree in them - except they don't.
I met the most beautiful red boy at a friends cattery who was a pretty good ringer for a British Shorthair, except he was a pure 100% moggie. He had been neutered late, was large and muscular, and had a massive round face, beautiful round eyes, small ears, was stocky with short legs and tail, and a lovely crisp coat. He also had a wonderful nature. When he planted his forehead on mine I could feel all my tension seeping away. He head butted, purred, rubbed, rolled and generally was a wonderfully confident, calm and outgoing cat. But he was not a British Shorthair despite his wonderful good looks.
The bottom line is that if a cat doesn't have and never had any papers, it's not a British Shorthair (or any other breed) whatever it looks like.
