I’m pretty sure he is an old English bantam
No, because Old English Game Bantams have a single comb and no muff/beard (feathers under and beside the beak).
Your chick has pea comb, and a beard. Not a big beard, but definitely present. It's part of why he does not have obvious wattles.
The only common kind of bantam in the USA that has both a beard and a pea comb is an Easter Egger bantam. (Ameraucana bantam would too, but is not common, and probably is not that color.)
