Stray Or Not?

I have made friends with this stray. The thing is I'm not sure if he is stray. He seems well taken care of but wears no collar. He is wary of humans and I'm the only exception. H e comes right up for pats and accepts food with no fuss. He seems to likes me heaps. I know not everyone collars there animals but there isn't even a small indent in his fur indicating he even had a collar. Maybe he was abandoned?

Some times he is with a friend kitty and he seems protective of his friend. However even if he was part of a colony he doesn't seem feral just wary of humans.

Should I try gain his trust and take him to a vet to see if he is microchipped?
