what cross/breed do you think my Rooster is?

Heres my lovely Roo, Knight. I got him for free from a farmer and Im trying to figure out what his background is. Any thoughts? I was thinking a cross with RIR and BA but not really sure, still learning all the breeds.

The first photo is him by his buff orpingtons to show his size. Any thoughts are appreciated

He looks a little like a Black Copper Marans, but he's probably a handsome mix.

Oh he could be! I wish I knew more about his background and where he came from. Hes a pretty boy. Thanks!
